What Is a Kegel Ball and How Can the Fun Factory Smartball Uno 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 people in the UK experience some degree of pelvic floor weakness — whether that's linked to childbirth, ageing, or simply never having focused on this group of muscles before. The kegel ball has become one of the most widely recommended tools for addressing this, and the Fun Factory Smartball Uno in White/India Red is a well-designed, body-safe option worth considering. Priced at just £17.99, it sits at an accessible price point without cutting corners on quality. You can also explore our wider range of women's health products if you're looking for complementary support.

The Smartball Uno is a single-ball pelvic floor trainer made from body-safe silicone and ABS plastic. It features a weighted inner ball that moves as you do, creating a gentle vibration that prompts your pelvic floor muscles to engage involuntarily. The retrieval cord makes removal straightforward, and the smooth surface is easy to clean. It's a product designed with real-world use in mind — not overly complicated, not intimidating for beginners.

How Does the Fun Factory Smartball Uno Work?

The mechanism here is elegantly simple. When inserted vaginally, the Smartball Uno sits against the pelvic floor muscles. The inner weighted ball rolls with your body's movement, producing a subtle vibration. This sensation triggers an involuntary muscular response — your pelvic floor contracts to hold the device in place. Over time, these repeated micro-contractions build strength and endurance in the levator ani and surrounding musculature.

Weighted inner ball creates gentle movement during normal activity
Pelvic floor muscles contract involuntarily to retain the device
Repeated contractions progressively strengthen the musculature
Can be used passively during everyday tasks such as walking or light housework

This passive training approach complements active kegel exercises — the kind the NHS recommends for managing stress urinary incontinence and improving pelvic tone.

Who Should Use the Fun Factory Smartball Uno?

This device is designed for adults with a vagina who want to proactively strengthen their pelvic floor. It's particularly well-suited to those who find it difficult to maintain a consistent routine of active kegel exercises, since the Smartball Uno does much of the work passively. That said, it's not appropriate for everyone.

Adults experiencing mild stress urinary incontinence (leaking when coughing, sneezing, or exercising)
Those looking to improve pelvic tone after childbirth — once cleared by a midwife or GP
People who want to enhance pelvic awareness and sexual sensation
Beginners to pelvic floor training who want a gentle starting point

It is not recommended during pregnancy, or if you have an active pelvic infection, unexplained pelvic pain, or have recently undergone pelvic surgery. Always seek advice from a healthcare professional if you're unsure whether this product is right for you.

How Does the Smartball Uno Compare to the Smartball Duo?

Feature	Smartball Uno (This Product)	Smartball Duo (Alternative)
Number of balls	1	2
Resistance level	Lighter — ideal for beginners	Greater — suited to intermediate users
Weight	Lighter overall	Heavier, more challenging
Price	£17.99	Higher price point

Is the Fun Factory Smartball Uno Clinically Safe to Use?

Yes — when used correctly and hygienically, this device is considered safe for most adults. The body-safe silicone exterior is non-porous, meaning it doesn't harbour bacteria when cleaned properly. Always wash the device with warm water and a mild, fragrance-free soap before and after each use. Store it in a clean, dry place away from direct sunlight. If you're also managing a condition like cystitis or a bladder infection, wait until you've fully recovered before resuming use.

As a kegel ball used for pelvic floor training, this product is a physical wellness device rather than a licensed medicine. However, if you have an underlying pelvic health condition, it's always sensible to speak with your GP or a pelvic health physiotherapist before starting any new training programme.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Fun Factory Smartball Uno - White/India Red

What Is the Fun Factory Smartball Uno and What Is It Used For?

The Fun Factory Smartball Uno is a single-ball pelvic floor training device designed to help strengthen the muscles of the pelvic floor through passive resistance. It is used by adults with a vagina who want to improve pelvic muscle tone, manage mild symptoms of stress urinary incontinence, or enhance pelvic awareness. The NHS recognises pelvic floor exercises as a first-line approach for managing urinary incontinence, and devices like this kegel ball can support that training by encouraging involuntary muscle engagement during everyday movement.

It is not a licensed medicinal product. It is a physical wellness device intended to complement — not replace — professional pelvic health advice or physiotherapy where that is indicated.

What Do You Need to Know Before Using the Fun Factory Smartball Uno?

Before using this device, it's important to consider whether it's appropriate for your current health situation. There are certain circumstances in which you should not use a kegel ball without first speaking to a healthcare professional.

Do not use this product if you:

Are currently pregnant
Have given birth within the last six weeks (or have not yet been cleared by your midwife or GP)
Have an active vaginal or pelvic infection
Have unexplained pelvic pain or pressure
Have recently undergone pelvic or abdominal surgery
Have a known allergy to silicone or ABS plastic
Have a prolapse that has not been assessed by a healthcare professional

Drug and product interactions:

No known drug interactions — this is a mechanical device
Do not use with silicone-based lubricants, as these can degrade the silicone surface; use water-based lubricants only
Avoid use alongside other intravaginal devices simultaneously

How Should You Use the Fun Factory Smartball Uno?

Using the Smartball Uno correctly is key to getting the most from your pelvic floor training. Take your time, especially if you're new to using any kind of internal device. There's no rush — starting gently and building up gradually is the right approach.

Wash the device thoroughly with warm water and mild, fragrance-free soap before first use and before every subsequent use.
Apply a generous amount of water-based lubricant to the ball and to your vaginal opening.
Find a comfortable position — lying down or squatting often works well for beginners.
Gently insert the Smartball Uno into the vagina, leaving the retrieval cord hanging outside the body.
Stand up and move around gently. The inner ball will begin to move, creating the training sensation.
Begin with 15 to 20 minutes per session. Gradually increase wear time as your muscles adapt.
To remove, relax your pelvic floor muscles and gently pull the retrieval cord.
Clean the device again after removal and store it in a clean, dry place.

Indication	User Group	Starting Duration	Maximum Duration
Pelvic floor strengthening	Beginners	15–20 minutes	Up to 30 minutes daily
Mild stress incontinence support	Adults (post-clearance)	20 minutes	Up to 30 minutes daily
Ongoing pelvic maintenance	Experienced users	20–30 minutes	No more than 2 hours at a time

What Are the Possible Side Effects of the Fun Factory Smartball Uno?

As a physical device rather than a medicine, the Smartball Uno does not carry pharmacological side effects. However, some users do experience physical discomfort, particularly when starting out. This is usually temporary and resolves as the muscles adapt.

Common experiences during initial use:

Mild pelvic pressure or a feeling of fullness
Temporary muscle soreness after sessions (similar to post-exercise ache)
Mild discomfort if inserted without sufficient lubrication

Less common concerns — stop use and seek advice if you notice:

Persistent or worsening pelvic pain
Unusual vaginal discharge or odour (which may indicate infection)
Difficulty removing the device
Any signs of an allergic reaction to the materials

If you're managing any ongoing pelvic health concerns alongside your training, our women's health collection includes a range of products that may offer additional support. And if you're exploring complementary intimate wellness options, you might also find our personal lubricants range useful — choosing the right lubricant matters when using any internal device.

How Should You Store the Fun Factory Smartball Uno?

Proper storage keeps the device hygienic and extends its lifespan. Silicone can attract dust and lint if left uncovered, so storing it correctly between uses is important.

Store in a clean, dry location away from direct sunlight and heat sources
Keep in the original pouch or a dedicated storage bag to prevent dust accumulation
Do not store alongside other silicone products, as prolonged contact can cause surface degradation
Keep out of reach of children
Do not store in extreme temperatures — avoid leaving in a car or near a radiator

Frequently Asked Questions

Where can I buy the Fun Factory Smartball Uno online in the UK?

You can buy the Fun Factory Smartball Uno directly from Cured Pharmacy for £17.99, with discreet delivery across the UK. It's available without a prescription and dispatched in plain, unmarked packaging. No need to visit a shop — ordering online is quick and straightforward.

How does a kegel ball work for pelvic floor training?

A kegel ball works by sitting inside the vagina and providing gentle internal resistance, which encourages the pelvic floor muscles to contract involuntarily in order to hold it in place. The weighted inner ball in the Smartball Uno moves with your body, creating a subtle vibration that amplifies this effect. Over time, these repeated contractions build strength and endurance in the pelvic floor musculature.

How do I insert the Fun Factory Smartball Uno step by step?

Start by washing the device with warm water and mild soap, then apply a water-based lubricant to both the ball and your vaginal opening. Find a comfortable position — lying down or squatting works well — and gently insert the Smartball Uno, leaving the retrieval cord outside the body. Once inserted, stand up and move around gently to activate the training effect.

How long should I wear the Smartball Uno each day?

Beginners should start with sessions of 15 to 20 minutes and gradually increase wear time as their muscles adapt. Most users aim for up to 30 minutes of daily use, which is sufficient to see progressive improvement in pelvic floor strength. You should never wear any kegel device for more than two hours at a time, as this can cause muscle fatigue rather than strengthening.

What are the side effects of using a kegel ball?

The most common experiences are mild pelvic pressure or temporary muscle soreness, particularly during the first few sessions — this is normal and similar to the ache you'd feel after any new exercise. If you experience persistent pain, unusual discharge, or difficulty removing the device, stop use immediately and speak to your GP. Choosing the right lubricant also matters; always use a water-based option to avoid irritation.

Who is the Fun Factory Smartball Uno suitable for?

It is suitable for adults with a vagina who want to strengthen their pelvic floor, including those experiencing mild stress urinary incontinence or those looking to improve pelvic tone after childbirth — once cleared by a healthcare professional. It is particularly well-suited to beginners, as the single-ball design offers lighter resistance than two-ball alternatives. It is not suitable for use during pregnancy or if you have an active pelvic infection.

Can I use the Smartball Uno if I have a prolapse?

If you have been diagnosed with a pelvic organ prolapse, you should speak to your GP or a pelvic health physiotherapist before using any internal pelvic floor device. In some cases, kegel training devices can be beneficial alongside supervised physiotherapy, but in others they may not be appropriate depending on the severity and type of prolapse. Always get professional clearance first.

What lubricant should I use with the Fun Factory Smartball Uno?

You should only use a water-based lubricant with the Smartball Uno, as silicone-based lubricants can degrade the silicone surface of the device over time. Our personal lubricants range includes several water-based options that are compatible with silicone devices. Apply lubricant generously before insertion to ensure comfort, especially if you are new to using internal devices.

What are the alternatives to the Fun Factory Smartball Uno?

The most direct alternative is the Fun Factory Smartball Duo, which features two balls and offers greater resistance — making it better suited to those who have already built some pelvic floor strength. Other options include different weighted kegel trainers from other brands, or simply performing NHS-recommended pelvic floor exercises without any device. If you're unsure which option suits you, a pelvic health physiotherapist can advise based on your individual needs.

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

Most people begin to notice improvements in pelvic floor strength and control within four to six weeks of consistent daily use. The NHS recommends performing pelvic floor exercises regularly over several months for lasting, meaningful results. Combining passive kegel ball training with active pelvic floor exercises tends to produce the best outcomes.

How do I clean the Fun Factory Smartball Uno?

Wash the device with warm water and a mild, fragrance-free soap before and after every use. The non-porous silicone surface does not harbour bacteria when cleaned properly, making hygiene straightforward. Do not submerge the device in boiling water or use harsh chemical cleaners, as these can damage the material.

Is the Fun Factory Smartball Uno safe to use long-term?

Yes — when used correctly and hygienically, the Smartball Uno is safe for ongoing, long-term pelvic floor training. The key is to avoid overuse: stick to sessions of no more than 30 minutes daily and never exceed two hours of continuous wear. If you notice any changes in pelvic comfort or function over time, consult a healthcare professional.

Can I use the Smartball Uno after having a baby?

You should wait until you have been cleared by your midwife or GP before using any internal pelvic floor device after childbirth — this is typically at your six-week postnatal check, though it may be longer depending on your recovery. Pelvic floor rehabilitation after birth is important, and a pelvic health physiotherapist can advise on the right time to introduce a device like this. Our women's health collection also includes other products that may support your postnatal recovery.

What is the latest research on kegel ball training for pelvic floor health?

Research consistently supports pelvic floor muscle training as an effective intervention for stress urinary incontinence, with the NHS recommending it as a first-line treatment. Studies suggest that weighted vaginal devices can enhance the effectiveness of pelvic floor training by providing proprioceptive feedback and encouraging involuntary contractions. A pelvic health physiotherapist can help you interpret what the evidence means for your specific situation.

Does the Fun Factory Smartball Uno help with bladder leakage?

It can support improvement in mild stress urinary incontinence — the type that causes leaking when you cough, sneeze, laugh, or exercise — by strengthening the pelvic floor muscles that support the bladder. However, it is not a medical treatment and should not replace professional assessment if your symptoms are moderate or severe. If bladder leakage is significantly affecting your quality of life, speak to your GP who can refer you to a specialist or pelvic health physiotherapist.

How Should You Use the Fun Factory Smartball Uno?

Using the Smartball Uno correctly makes all the difference to both comfort and results. Take your time with each step, especially if you're new to pelvic floor training devices — there's no benefit to rushing.

What Is the Correct Dose of the Fun Factory Smartball Uno?

There is no pharmacological dose for this device, but wear duration and frequency are the equivalent consideration. Starting gently and building up gradually is the clinically sensible approach — your pelvic floor muscles need time to adapt, just like any other muscle group.

When Is the Best Time to Use the Fun Factory Smartball Uno?

There is no single "correct" time — the Smartball Uno is designed to fit into your daily routine naturally. Many users find it easiest to wear during light household tasks, a gentle walk, or other low-impact activities where movement activates the inner ball. Avoid wearing it during high-impact exercise, swimming, or sexual activity.

Consistency matters more than timing. Choosing a regular slot in your day — perhaps during your morning routine or an afternoon walk — helps you build the habit that leads to real, lasting improvement in pelvic floor strength.

How Long Can You Use the Fun Factory Smartball Uno For?

The Smartball Uno is suitable for ongoing, long-term use as part of a regular pelvic floor training routine. Most people begin to notice meaningful improvements within four to six weeks of consistent daily use, though continuing beyond this point helps maintain and build on those gains. Never wear the device for more than two hours in a single session, as prolonged use can cause muscle fatigue rather than strengthening.

If you experience any discomfort, unusual symptoms, or feel that your pelvic floor concerns are not improving, speak to your GP or a pelvic health physiotherapist who can assess your progress and adjust your training plan accordingly.

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

What Are the Most Common Side Effects of the Fun Factory Smartball Uno?

Because the Smartball Uno is a physical training device rather than a medicine, it does not carry pharmacological side effects. However, some users — particularly those new to pelvic floor training — do experience physical sensations during or after use that are worth knowing about. These are generally mild and temporary.

Mild pelvic pressure or a feeling of fullness during wear
Temporary muscle soreness or aching after sessions, similar to post-exercise fatigue
Mild discomfort during insertion if insufficient lubricant is used
A sensation of heaviness in the pelvic region, particularly in the first few sessions

What Are the Less Common Side Effects of the Fun Factory Smartball Uno?

Less commonly, some users may experience issues that go beyond normal training sensations. These are not typical but are important to be aware of so you can respond appropriately if they occur.

Persistent pelvic discomfort that does not resolve after removing the device
Localised irritation or redness at the vaginal opening, which may indicate sensitivity to the materials or lubricant used
A feeling of increased pelvic pressure when standing, which may suggest the device is not positioned correctly
Difficulty removing the device — this is rare but can occur if the pelvic floor muscles are very tense

What Are the Serious Side Effects of the Fun Factory Smartball Uno?

Serious adverse effects from using a kegel ball are uncommon when the device is used correctly and hygienically. However, there are certain signs that should prompt you to stop use immediately and seek medical advice. Unusual vaginal discharge with an unpleasant odour, persistent or worsening pelvic pain, or any signs of an allergic reaction — such as swelling, itching, or a rash — all warrant prompt attention from a healthcare professional. Using the device during an active vaginal or pelvic infection can worsen the infection and should be avoided entirely.

What Should You Do If You Experience Side Effects?

If you notice any discomfort beyond mild, temporary muscle soreness, the first step is to remove the device and rest. Most minor sensations resolve quickly once the device is out. If symptoms persist — particularly pain, discharge, or any sign of infection — contact your GP or a sexual health clinic for assessment. Do not reinsert the device until you have been assessed and any underlying issue has been resolved. For ongoing pelvic health concerns, a referral to a pelvic health physiotherapist is often the most helpful next step.

Can the Fun Factory Smartball Uno Interact With Other Products?

As a mechanical device, the Smartball Uno has no pharmacological interactions with medicines. However, there are important product compatibility considerations. Silicone-based lubricants should never be used with this device, as they can degrade the silicone surface over time, potentially compromising hygiene and safety. Always use a water-based lubricant. Additionally, avoid using the Smartball Uno simultaneously with other intravaginal devices, and do not use it if you are currently using any intravaginal medication — such as pessaries or topical treatments — without first speaking to your pharmacist.

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