How do kegel balls work for pelvic floor training?

Kegel balls work by providing gentle internal resistance that encourages the pelvic floor muscles to contract involuntarily during normal movement, gradually building strength over time.

How do I insert the Fun Factory Smartballs Duo correctly?

Apply a water-based lubricant to the balls, insert the first ball vaginally, then gently push the second ball in behind it, leaving the retrieval cord outside the body for easy removal.

Are kegel balls safe to use after childbirth?

You should wait until your postnatal check (usually around 6 to 8 weeks after delivery) and receive clearance from your GP or midwife before using kegel balls postpartum.

What are the side effects of using kegel balls?

Some users experience mild vaginal discomfort or temporary pelvic muscle fatigue, particularly during initial use. Discontinue use and consult a healthcare professional if you experience pain or unusual discharge.

What is the difference between single and dual kegel balls?

Single kegel balls are lighter and better suited to beginners, while dual kegel balls like the Smartballs Duo offer greater resistance and are more appropriate for those with some existing pelvic floor strength.

What Are Kegel Balls and How Can They Help You?

If you've been looking for a simple, discreet way to work on your pelvic floor, you're far from alone. Millions of women in the UK experience some degree of pelvic floor weakness — whether that's after childbirth, during the menopause, or simply as a result of ageing. The Fun Factory Smartballs Duo are kegel balls designed to make pelvic floor training feel less like a chore and more like something you can fit naturally into your day. Priced at just £12.95, they offer an accessible entry point into pelvic floor care. You can explore more intimate health products in our women's health collection.

The Smartballs Duo from Fun Factory feature a dual-ball design encased in body-safe silicone, with a retrieval cord for easy removal. The black colourway is discreet and the soft outer material is gentle on sensitive tissue. These are not a medical device in the prescription sense — they're an over-the-counter intimate care product — but the pelvic floor benefits they support are well-documented in clinical literature.

How Do the Fun Factory Smartballs Duo Work?

The mechanism is elegantly straightforward. Inside each ball sits a smaller weighted ball that moves freely. As you go about your normal daily activities — walking, standing, even light housework — the inner balls shift and roll, creating subtle vibrations. Your pelvic floor muscles respond to these micro-movements by contracting involuntarily to keep the device in place. Over time, this passive resistance builds muscular endurance and tone.

Inner weighted balls create gentle movement during normal activity
Pelvic floor muscles contract reflexively to retain the device
Repeated contractions gradually strengthen the levator ani muscle group
Consistent use may improve bladder control and pelvic support

Think of it like a low-level workout happening in the background. You don't need to set aside dedicated exercise time — the training happens as you move.

Who Is Suitable for Using the Smartballs Duo?

These kegel balls are designed for adult women who want to proactively support their pelvic floor health. They're particularly relevant if you've noticed mild stress urinary incontinence — that small leak when you sneeze or laugh — or if you're approaching or going through the menopause, when oestrogen decline can affect pelvic tissue tone.

Women experiencing mild stress urinary incontinence
Those looking to maintain pelvic floor strength as a preventative measure
Women who have completed postnatal recovery and received GP clearance
Anyone wanting a discreet, passive approach to pelvic floor exercise

They are not suitable for use during pregnancy, in the immediate postpartum period, or if you have an active pelvic infection, pelvic organ prolapse, or have recently had pelvic surgery. Always speak to your GP or pelvic health physiotherapist if you're unsure.

How Do the Smartballs Duo Compare to Single Kegel Balls?

Feature	Smartballs Duo (Dual)	Single Kegel Ball
Number of balls	Two	One
Resistance level	Higher — suits intermediate users	Lower — better for beginners
Weighted inner balls	Yes — dual movement	Yes — single movement
Retrieval cord	Yes	Yes
Suitable for beginners	With gradual introduction	Yes — ideal starting point

Are the Smartballs Duo Body-Safe and Easy to Store?

Yes. The outer casing is made from body-safe silicone, which is non-porous, hypoallergenic, and easy to clean. This matters enormously for any product used internally. Always wash the Smartballs Duo with warm water and a mild, fragrance-free soap before and after each use, and allow them to dry fully before storing. If you're also managing vaginal health concerns such as recurrent thrush, you may find our thrush treatment collection a useful companion resource.

Store the device in its original pouch or a clean, dry container, away from direct sunlight and extreme temperatures. Do not use silicone-based lubricants with silicone toys — always opt for a water-based personal lubricant to preserve the material integrity. These kegel balls are designed for repeated, long-term use when cared for correctly.

This product is a non-medicated intimate care device. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Fun Factory Smartballs Duo Kegel Balls Black

What Are the Fun Factory Smartballs Duo and What Are They Used For?

The Fun Factory Smartballs Duo are a dual-ball pelvic floor training device intended for adult women. They are used to support the strengthening of the pelvic floor musculature — the group of muscles and connective tissue that supports the bladder, bowel, and uterus. Weak pelvic floor muscles are associated with stress urinary incontinence, reduced sexual sensation, and pelvic organ prolapse risk. The NHS recommends pelvic floor exercises as a first-line approach for managing these concerns, and devices like kegel balls can complement that training by providing passive resistance during everyday movement.

This is not a medicinal product. It contains no active pharmaceutical ingredients. Its benefits are mechanical — the weighted inner balls encourage involuntary pelvic floor contractions as you move, gradually building strength over weeks of consistent use.

What Do You Need to Know Before Using the Smartballs Duo?

Before using these kegel balls, it's important to consider whether they are appropriate for your current health status. There are several situations where use is not recommended without professional guidance.

Do not use if you:

Are currently pregnant
Are within 6–8 weeks of giving birth (vaginal or caesarean) and have not yet had your postnatal check
Have a diagnosed pelvic organ prolapse (without physiotherapist approval)
Have an active vaginal or pelvic infection
Have recently undergone pelvic or abdominal surgery
Experience pain during vaginal insertion of any kind
Have vaginismus or vulvodynia

Drug and product interactions:

No known drug interactions — this is a non-medicated device
Do not use silicone-based lubricants alongside silicone devices — use water-based lubricants only
Avoid use alongside vaginal pessaries or medicated vaginal treatments without GP advice

How Should You Use the Fun Factory Smartballs Duo?

Using the Smartballs Duo correctly is straightforward, but taking your time on the first occasion makes a real difference to comfort. Always clean the device thoroughly before first use and before every subsequent session.

Wash the Smartballs Duo with warm water and mild, fragrance-free soap. Rinse and dry fully.
Apply a generous amount of water-based lubricant to the first ball.
Find a comfortable position — lying down or with one foot raised on a step works well for most people.
Gently insert the first ball vaginally, then ease the second ball in behind it.
Ensure the retrieval cord remains outside the body at all times.
Stand up and go about your normal activities. Your pelvic floor will do the work.
To remove, relax your pelvic floor muscles and gently pull the retrieval cord. Bear down slightly if needed.
Wash the device again after removal and store it clean and dry.

Indication	User Group	Starting Duration	Frequency
Pelvic floor strengthening	Adult women (general)	15–20 minutes	Daily or most days
Post-recovery pelvic support	Post-postnatal check (GP cleared)	10–15 minutes initially	Daily, building gradually
Maintenance training	Experienced users	Up to 2 hours	Several times per week

If you're also exploring other aspects of intimate health, our personal lubricants collection includes water-based options that are compatible with silicone devices.

What Are the Possible Side Effects of the Smartballs Duo?

Because this is a mechanical device rather than a medicine, side effects are generally mild and related to physical use rather than pharmacological action.

Common side effects:

Mild vaginal discomfort or pressure during initial use
Temporary pelvic muscle fatigue after wearing
Slight awareness of the device during movement (this typically reduces with regular use)

Less common side effects:

Vaginal irritation if lubricant is not used or if the device is not cleaned properly
Difficulty removing the device if pelvic floor muscles are very tense — relaxing and bearing down gently resolves this in most cases
Pelvic discomfort if worn for too long, particularly in the early stages of use

Stop using the device and consult your GP if you experience pain, unusual discharge, or any signs of infection. You can also find support for related concerns through our cystitis and bladder infection collection if urinary symptoms arise.

How Should You Store the Fun Factory Smartballs Duo?

Store in a clean, dry location away from direct sunlight
Keep in the original storage pouch or a dedicated clean container
Do not store near sharp objects that could damage the silicone surface
Keep away from extreme heat or cold
Ensure the device is fully dry before storing to prevent bacterial growth
Keep out of reach of children

Frequently Asked Questions

Where can I buy Fun Factory Smartballs Duo kegel balls online in the UK?

You can buy the Fun Factory Smartballs Duo kegel balls directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for £12.95. Orders are dispatched with discreet packaging so there's nothing to identify the contents on the outside. You can also browse our wider women's health collection for related intimate care products.

How do kegel balls work to strengthen the pelvic floor?

Kegel balls work by placing a weighted device inside the vagina that moves gently as you go about your day. The pelvic floor muscles contract involuntarily to hold the device in place, which over time builds muscular strength and endurance. This passive training approach complements active pelvic floor exercises recommended by the NHS.

How do I insert the Fun Factory Smartballs Duo step by step?

Start by washing the device thoroughly with warm water and mild soap, then apply a water-based lubricant to the first ball. Insert the first ball vaginally, then gently ease the second ball in behind it, ensuring the retrieval cord remains outside the body at all times. If you experience any discomfort during insertion, stop and consult a healthcare professional.

How long should I wear kegel balls each day as a beginner?

If you're new to pelvic floor training devices, start with just 15 to 20 minutes per day and see how your body responds before increasing wear time. Most people find they can comfortably extend sessions to 30–60 minutes after a few weeks of regular use. Never wear kegel balls for more than 2 hours in a single session.

Are kegel balls safe to use after having a baby?

You should wait until after your postnatal check — typically at 6 to 8 weeks after delivery — and receive explicit clearance from your GP or midwife before using kegel balls. This applies whether you had a vaginal birth or a caesarean section, as pelvic floor recovery takes time in both cases. Starting too early can cause harm rather than help.

Can I use kegel balls if I have a pelvic organ prolapse?

No — you should not use kegel balls if you have a diagnosed pelvic organ prolapse without first consulting your GP or a specialist pelvic health physiotherapist. In some cases of mild prolapse, supervised pelvic floor training may be appropriate, but this needs to be assessed individually. Using kegel balls without guidance in this situation could worsen symptoms.

What are the possible side effects of using kegel balls?

Most people experience no significant side effects, though mild vaginal discomfort or a sense of pressure is common during the first few uses. Temporary pelvic muscle fatigue after wearing is also normal, particularly if you've been inactive for a while. If you notice pain, unusual discharge, or any signs of irritation, remove the device and speak to your GP.

What lubricant should I use with the Fun Factory Smartballs Duo?

Always use a water-based lubricant with the Smartballs Duo — silicone-based lubricants can degrade the silicone outer casing over time, compromising the material's integrity and hygiene. A small amount applied to the first ball before insertion makes the process much more comfortable. You can find compatible options in our personal lubricants collection.

What is the difference between the Smartballs Duo and a single kegel ball?

The Smartballs Duo features two connected balls, which creates greater resistance and is better suited to women who already have some pelvic floor strength. A single kegel ball is lighter and less demanding, making it a more appropriate starting point for complete beginners. If you're unsure which to start with, a pelvic health physiotherapist can advise based on your current muscle tone.

How do I clean and care for the Fun Factory Smartballs Duo?

Wash the device with warm water and a mild, fragrance-free soap before and after every use, then rinse thoroughly and allow to dry completely before storing. Do not submerge the device in boiling water or use harsh chemical cleaners, as these can damage the silicone. Store in a clean, dry pouch away from direct sunlight and sharp objects.

How long does it take to see results from using kegel balls?

Most women notice some improvement in pelvic floor awareness and control within 4 to 6 weeks of consistent daily use, though this varies depending on your starting level of muscle tone. Significant improvements in symptoms like stress urinary incontinence may take 3 months or longer of regular training. Combining kegel ball use with active pelvic floor exercises tends to produce faster results.

Who is eligible to use the Fun Factory Smartballs Duo?

The Smartballs Duo are suitable for adult women who are not pregnant, are not in the immediate postpartum recovery period, and do not have an active pelvic infection, prolapse, or recent pelvic surgery. They are appropriate for women at any stage of life who want to proactively maintain or improve pelvic floor strength. If you have any underlying health conditions affecting the pelvic region, consult your GP first.

Can I wear kegel balls during exercise or physical activity?

Light to moderate activity such as walking, yoga, or gentle housework is generally fine and actually enhances the passive training effect of kegel balls. However, high-impact activities like running, jumping, or heavy lifting are not recommended while wearing them, as this can place excessive strain on the pelvic floor. Always listen to your body and remove the device if you feel any discomfort.

How long can I continue using kegel balls safely?

Kegel balls can be used as part of an ongoing pelvic floor maintenance routine for as long as they remain comfortable and the device is in good condition. There is no fixed maximum duration of use, provided you are not experiencing any adverse effects. Inspect the device regularly for any signs of wear, cracking, or damage to the silicone, and replace it if the integrity is compromised.

What are the latest findings on kegel ball effectiveness for pelvic floor training?

Clinical evidence supports pelvic floor muscle training as an effective intervention for stress urinary incontinence, and weighted vaginal devices are used as adjuncts to this training in some physiotherapy settings. The NHS recommends pelvic floor exercises as a first-line treatment for urinary incontinence, and devices like kegel balls may help women maintain consistent engagement with their training. Always combine device use with active exercises for the most clinically meaningful outcomes.

How Should You Use the Fun Factory Smartballs Duo?

Using the Smartballs Duo correctly from the outset ensures both comfort and effectiveness. Before your very first use, wash the device thoroughly with warm water and a mild, fragrance-free soap, rinse well, and allow it to dry completely. Never skip this step — hygiene is essential for any product used internally.

What Is the Correct Dose of the Fun Factory Smartballs Duo?

There is no pharmaceutical dose for this device, but wear duration and frequency are the equivalent consideration. Starting conservatively and building up gradually is the safest approach, particularly if you are new to pelvic floor training devices or are returning to exercise after childbirth.

When Is the Best Time to Use the Fun Factory Smartballs Duo?

The beauty of this device is its flexibility — there is no single "best" time, because it works passively during normal movement. Many women find it easiest to incorporate into their morning routine, wearing the device during light household tasks, a gentle walk, or while working from home. Avoid wearing during high-impact exercise, swimming, or any activity that involves significant physical strain.

Consistency matters more than timing. Wearing the device at roughly the same time each day helps build a habit, which in turn leads to more reliable pelvic floor improvement over weeks and months.

How Long Can You Use the Fun Factory Smartballs Duo For?

There is no fixed maximum duration of use for this product, provided it remains comfortable and the device is in good condition. Many women incorporate kegel ball training into their long-term pelvic health routine indefinitely. Inspect the silicone surface regularly for any signs of cracking, discolouration, or damage — replace the device if the material integrity is compromised.

If you experience persistent discomfort, worsening urinary symptoms, or any pelvic pain during or after use, stop and consult your GP or a pelvic health physiotherapist before continuing.

Do not exceed the recommended wear duration. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of the Fun Factory Smartballs Duo?

Because the Smartballs Duo is a mechanical device rather than a medicine, side effects are generally mild and related to physical use. Most women tolerate the device well, particularly once they've had a few sessions to adjust.

Mild vaginal pressure or a sense of fullness during initial use
Temporary pelvic muscle fatigue after wearing, especially in the first few weeks
Slight awareness of the device during movement — this typically fades with regular use

What Are the Less Common Side Effects of the Fun Factory Smartballs Duo?

Less frequently, some users may experience the following. These are usually related to incorrect use, insufficient lubrication, or wearing the device for too long in the early stages.

Vaginal irritation or mild soreness if lubricant is not used
Difficulty removing the device if pelvic floor muscles are very tense — relaxing and bearing down gently resolves this in most cases
Pelvic discomfort or aching if worn for longer than recommended
Mild lower abdominal awareness after extended wear

What Are the Serious Side Effects of the Fun Factory Smartballs Duo?

Serious side effects are rare but important to be aware of. If you notice any of the following, remove the device immediately and seek medical advice.

Significant pelvic or vaginal pain during or after use
Unusual vaginal discharge or odour following use
Signs of vaginal infection such as increased discharge, itching, or burning
Worsening urinary symptoms, including increased urgency or leakage
Inability to remove the device — seek medical assistance promptly

What Should You Do If You Experience Side Effects?

For mild discomfort, try reducing your wear time and ensuring you are using an adequate amount of water-based lubricant. Give your body time to adjust — most initial discomfort resolves within the first week or two of use. If symptoms persist beyond this point, or if you experience anything more than mild discomfort, stop using the device and speak to your GP.

Do not attempt to push through significant pain. Pelvic floor training should feel like gentle effort, not discomfort. A pelvic health physiotherapist can assess your technique and advise on whether this type of device is appropriate for your individual anatomy and muscle tone.

Can the Fun Factory Smartballs Duo Interact With Other Products?

This is a non-medicated device with no known drug interactions. However, there are a few important product compatibility points to be aware of. Do not use silicone-based lubricants with this device, as they can degrade the silicone outer casing over time. Avoid using the device simultaneously with vaginal pessaries, medicated vaginal creams, or suppositories without first consulting your GP, as concurrent use may affect the efficacy of those treatments or cause irritation.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
