What Are Kegel Balls and How Can They Help You?

 

The Fun Factory Smartball Uno is a single kegel balls device designed to help you strengthen your pelvic floor muscles through gentle, passive resistance training. Pelvic floor weakness is incredibly common — the NHS estimates that one in three women who have had a baby will experience some degree of urinary incontinence, and pelvic floor exercises are consistently recommended as a first-line approach to managing it. This sleek, body-safe device from Fun Factory makes that training more accessible and, frankly, a lot easier to stick to than remembering to squeeze on your own. If you're looking for a discreet, effective way to support your pelvic health, you'll find a range of relevant products in our women's health collection.

Priced at just £9.95, the Smartball Uno is an entry-level option that doesn't compromise on quality. The outer casing is made from body-safe silicone, and the inner weighted ball creates subtle movement that naturally engages your pelvic floor as you move throughout the day. It comes in black and includes a retrieval cord for safe, easy removal.

 

How Does the Fun Factory Smartball Uno Work?

 

The mechanism is elegantly simple. When inserted vaginally, the weighted inner ball shifts with your body's movement. Your pelvic floor muscles instinctively contract to hold the device in place — this is the passive training effect. Over time, repeated engagement builds muscular endurance and tone, much like any other resistance-based exercise.

  • The outer silicone shell sits comfortably inside the vaginal canal
  • The inner weighted ball moves freely, creating gentle vibration-like feedback
  • Pelvic floor muscles contract reflexively to stabilise the device
  • Consistent use progressively strengthens the levator ani and surrounding musculature

 

Who Should Consider Using the Smartball Uno?

 

This device is well suited to adult women at various life stages. Whether you're postpartum, perimenopausal, or simply want to be proactive about your pelvic health, it offers a practical starting point. It's particularly relevant if you've noticed any of the following:

  • Mild stress urinary incontinence (leaking when you cough, sneeze, or exercise)
  • Reduced pelvic floor tone following vaginal delivery
  • A desire to maintain pelvic muscle strength as a preventive measure
  • Difficulty maintaining consistent voluntary kegel exercise routines

It is not suitable for use during pregnancy, immediately following pelvic or abdominal surgery, or if you have an active pelvic infection. If you're unsure whether this device is right for you, speak to your GP or a pelvic floor physiotherapist before use.

 

How Does the Smartball Uno Compare to Other Pelvic Floor Trainers?

 

Feature Fun Factory Smartball Uno Double Kegel Ball Set
Number of balls Single Two
Difficulty level Beginner-friendly Intermediate to advanced
Resistance level Lower Higher
Recommended for New users, postpartum recovery Experienced users seeking progression

 

Is the Smartball Uno Clinically Safe to Use?

 

Yes — when used correctly, this type of device is considered safe for most adult women. The body-safe silicone material is non-porous, hypoallergenic, and easy to clean, which significantly reduces the risk of irritation or infection. The NHS recommends pelvic floor exercises for women experiencing urinary incontinence, and devices like kegel balls can support that training when used appropriately. You can also explore our cystitis and bladder infection collection if you're managing related urinary health concerns alongside your pelvic floor training.

Store the device in a clean, dry location away from direct sunlight. Clean thoroughly with warm water and mild soap or a dedicated toy cleaner before and after each use.

This product is a medical 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 Smartball Uno Kegel Balls Black

 

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 intended for use by adult women. It is used to strengthen the pelvic floor musculature — the group of muscles and connective tissues that support the bladder, uterus, and bowel. Weak pelvic floor muscles are associated with stress urinary incontinence, pelvic organ prolapse, and reduced sexual sensation. The NHS recommends pelvic floor exercises as a first-line treatment for stress urinary incontinence, and this device is designed to make that training more consistent and effective by providing passive resistance during everyday movement.

It is not a medicinal product and contains no active pharmaceutical ingredients. It works purely through mechanical means — the movement of the weighted inner ball encourages involuntary pelvic floor contractions, building strength over time with regular use.

 

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

 

Before using this device, it's important to consider whether it is appropriate for your current health situation. There are certain circumstances in which use is not recommended.

Do not use this product if you:

  • Are currently pregnant
  • Have given birth within the last six weeks (vaginal or caesarean delivery)
  • Have recently undergone pelvic, abdominal, or gynaecological surgery
  • Have an active vaginal or pelvic infection
  • Have been diagnosed with vaginismus or significant pelvic pain disorders
  • Have a known allergy or sensitivity to silicone

Drug and product interactions:

  • No known drug interactions — this is a mechanical device, not a medicine
  • Do not use oil-based lubricants with silicone devices, as these can degrade the material; use water-based lubricants only

If you have any concerns about pelvic floor health or urinary symptoms, it is always worth speaking to your GP. You may also find it helpful to browse our condoms and sexual health collection for related products.

 

How Should You Use the Fun Factory Smartball Uno?

 

Using the Smartball Uno correctly is straightforward, but it's worth taking your time, especially if this is your first experience with a pelvic floor trainer. Always clean the device thoroughly before and after each use.

  1. Wash the device with warm water and mild soap, then rinse and dry completely
  2. Apply a generous amount of water-based lubricant to the ball
  3. Find a comfortable position — lying down or squatting works well for insertion
  4. Gently insert the ball vaginally, leaving the retrieval cord outside the body
  5. Stand up and go about your normal daily activities for the recommended duration
  6. To remove, relax your pelvic floor muscles and gently pull the retrieval cord
  7. Clean the device again after removal and store in a clean, dry place
Indication User Group Session Duration Frequency
Pelvic floor strengthening (beginner) Adult women, new users 15–20 minutes Daily or 5 days per week
Maintenance / ongoing training Experienced users Up to 60 minutes Daily
Postpartum recovery (after 6 weeks) Postnatal women, GP-cleared 15 minutes initially Daily, with gradual increase

 

What Are the Possible Side Effects of the Smartball Uno?

 

As a mechanical device rather than a medicine, the Smartball Uno does not carry the same side effect profile as pharmaceutical products. However, some users do experience mild physical responses, particularly when starting out.

Common side effects:

  • Mild pelvic discomfort or pressure during initial use
  • Temporary muscle soreness after sessions, similar to post-exercise fatigue
  • Mild vaginal irritation if insufficient lubricant is used

Less common side effects:

  • Difficulty removing the device (relax pelvic muscles fully and try again; if persistent, seek medical advice)
  • Increased urinary urgency in the short term as muscles adapt
  • Localised discomfort if used for longer than recommended periods

Stop using the device immediately and consult your GP if you experience pain, unusual discharge, bleeding, or any signs of infection. If you're managing related urinary symptoms, our cystitis and bladder infection section may also be useful.

 

How Should You Store the Fun Factory Smartball Uno?

 

  • Store in a clean, dry location away from direct sunlight
  • Keep away from extreme heat or cold, which can affect the silicone material
  • Store separately from other devices to avoid surface damage
  • Use the original pouch or a clean cotton bag for storage
  • Keep out of reach of children
  • Do not store with oil-based products that could degrade the silicone

Frequently Asked Questions

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

You can buy the Fun Factory Smartball Uno kegel balls directly from Cured Pharmacy online for £9.95 with discreet delivery. No prescription is required, as this is an over-the-counter pelvic floor training device. It is also available alongside other sexual and reproductive health products in our condoms and sexual health collection.

How do kegel balls work in the body?

Kegel balls work by providing gentle internal resistance that prompts your pelvic floor muscles to contract involuntarily in order to hold the device in place. The weighted inner ball shifts with your body's natural movement, creating a passive training stimulus throughout the day. Over time, this repeated muscular engagement builds strength and endurance in the pelvic floor.

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

Apply a water-based lubricant to the device, then gently insert it vaginally while in a comfortable position such as lying down or squatting, leaving the retrieval cord outside the body. Wear it for 15 to 20 minutes initially while going about your normal activities. To remove, relax your pelvic floor muscles fully and pull gently on the retrieval cord.

How long should I use kegel balls each day for best results?

Beginners should start with sessions of 15 to 20 minutes and gradually increase duration as their pelvic floor muscles adapt and strengthen. Most pelvic floor physiotherapists recommend daily or near-daily use for at least four to six weeks to notice meaningful improvement. Avoid wearing the device for more than two hours at a time, particularly in the early stages of training.

Are there any side effects of using kegel balls?

Most women tolerate kegel balls well, but some experience mild pelvic discomfort, temporary muscle soreness, or mild vaginal irritation — particularly when starting out. These effects are usually short-lived and resolve as your body adjusts. If you experience pain, unusual discharge, or bleeding, remove the device immediately and consult your GP.

Who is the Fun Factory Smartball Uno suitable for?

The Smartball Uno is suitable for adult women who want to strengthen their pelvic floor muscles, including those experiencing mild stress urinary incontinence or those looking to restore pelvic tone after childbirth. It is an entry-level device, making it ideal for beginners who have not used a pelvic floor trainer before. It is not suitable for use during pregnancy, immediately after pelvic surgery, or if you have an active pelvic infection.

Can I use kegel balls after having a baby?

You should wait at least six weeks after a vaginal delivery before using any internal pelvic floor device, and ideally until you have been cleared by your GP or midwife at your postnatal check. Starting too early can interfere with healing of perineal tissue. Once cleared, the Smartball Uno can be a helpful tool for rebuilding pelvic floor strength postpartum.

What are the alternatives to the Fun Factory Smartball Uno?

Alternatives include double kegel ball sets, weighted vaginal cones, or guided pelvic floor physiotherapy with a specialist. The Smartball Uno is a single-ball, beginner-friendly option — once you've built strength, you might progress to a heavier or dual-ball design. You can also explore our women's health collection for other pelvic and urinary health products.

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

Most women begin to notice improvements in pelvic floor tone and bladder control within four to six weeks of consistent daily use. More significant changes — such as reduced leakage during exercise or sneezing — may take up to three months of regular training. Consistency is key; sporadic use is unlikely to produce lasting results.

What is the correct way to clean the Smartball Uno?

Wash the device thoroughly with warm water and a mild, fragrance-free soap before and after every use, then rinse well and allow it to dry completely before storing. You can also use a dedicated intimate toy cleaner if preferred. Avoid submerging the device in boiling water or using harsh chemical cleaners, as these can damage the silicone surface.

Can I use any lubricant with the Fun Factory Smartball Uno?

Only water-based lubricants should be used with silicone devices like the Smartball Uno. Oil-based lubricants can degrade silicone over time, compromising the material's integrity and hygiene. Silicone-based lubricants should also be avoided, as they can react with the device's surface.

What happens if I cannot remove the Smartball Uno?

If you have difficulty removing the device, try relaxing your pelvic floor muscles fully — bearing down gently as if having a bowel movement can help. Changing position, such as squatting, may also make removal easier. If you are still unable to remove it after several attempts, seek medical assistance from your GP or nearest urgent care centre.

Is the Fun Factory Smartball Uno body-safe?

Yes — the Smartball Uno is made from body-safe silicone, which is non-porous, hypoallergenic, and free from phthalates and latex. This makes it a safe choice for internal use, provided it is cleaned properly between uses. If you have a known sensitivity to silicone, consult your GP before use.

What does the latest research say about kegel balls for pelvic floor training?

Research supports the use of pelvic floor muscle training — including with weighted vaginal devices — as an effective intervention for stress urinary incontinence in women. NICE guidelines recommend supervised pelvic floor muscle training as a first-line treatment, and devices like kegel balls can complement this approach. The NHS also endorses pelvic floor exercises as a safe, evidence-based strategy for improving bladder control.

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 beneficial. There is no set maximum duration of use, provided you follow the recommended session lengths and maintain good hygiene. If you develop any discomfort or symptoms over time, take a break and speak to your GP or a pelvic floor physiotherapist.

How Should You Use the Fun Factory Smartball Uno?

Using the Smartball Uno correctly ensures you get the most from each training session while keeping yourself comfortable and safe. Always clean the device with warm water and mild soap before and after every use, and apply a water-based lubricant before insertion.

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

There is no pharmaceutical dose for this device, but session duration and frequency are important for safe, effective training. Starting with shorter sessions and building up gradually helps your pelvic floor muscles adapt without becoming fatigued or strained.

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

The Smartball Uno is designed to be worn during everyday activities, so there is no single "best" time — it fits around your routine. Many women find it convenient to wear during light household tasks, a gentle walk, or while working from home, as natural body movement enhances the passive training effect.

Avoid wearing the device during high-impact exercise, swimming, or any activity that involves significant physical exertion, particularly in the early stages of use. It should not be worn during sexual intercourse or while sleeping.

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

The Smartball Uno can be incorporated into your long-term pelvic floor health routine indefinitely, provided it remains comfortable and you continue to maintain good hygiene practices. There is no fixed treatment course — many women use pelvic floor trainers as an ongoing preventive measure rather than a short-term intervention.

If you notice any discomfort, increased urinary symptoms, or irritation developing over time, take a break from use and consult your GP or a pelvic floor physiotherapist. As your strength improves, you may wish to progress to a heavier or dual-ball device for continued challenge.

Do not exceed the recommended session duration. 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 mechanical device rather than a medicine, it does not carry a pharmacological side effect profile. However, some women do experience mild physical responses, particularly during the first few sessions as their body adjusts to the sensation and the muscular demands of training.

  • Mild pelvic pressure or a sensation of fullness during use
  • Temporary pelvic floor muscle soreness after sessions, similar to post-exercise fatigue
  • Mild vaginal irritation if insufficient water-based lubricant is used
  • A slight increase in urinary urgency in the early stages of training

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

Less commonly, some users report experiences that may require a short break from use or a review of technique. These are generally related to overuse or incorrect insertion rather than any inherent risk of the device itself.

  • Difficulty removing the device due to strong pelvic floor contractions — relaxing fully and changing position usually resolves this
  • Localised discomfort or cramping if worn for longer than the recommended duration
  • Mild skin sensitivity around the vaginal opening, particularly in women with sensitive tissue

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

Serious adverse effects are rare when the device is used correctly and kept clean. However, you should be aware of signs that warrant prompt medical attention. Do not ignore these symptoms or attempt to self-manage them.

  • Significant pelvic pain during or after use
  • Unusual vaginal discharge with an unpleasant odour — this may indicate infection
  • Any vaginal bleeding not associated with your menstrual cycle
  • Inability to remove the device after multiple attempts

What Should You Do If You Experience Side Effects?

If you experience mild discomfort, try reducing your session duration and ensuring you are using adequate water-based lubrication. Give your pelvic floor muscles a rest day between sessions if soreness persists. For any symptoms that concern you — particularly pain, bleeding, or signs of infection — remove the device immediately and contact your GP or call NHS 111 for guidance.

Never continue using the device through significant pain. Your body's response is a useful guide, and discomfort that doesn't resolve quickly should always be assessed by a healthcare professional.

Can the Fun Factory Smartball Uno Interact With Other Products or Medicines?

As a mechanical device, the Smartball Uno has no known interactions with medicines. However, there are important product compatibility considerations. Oil-based lubricants and silicone-based lubricants can degrade the silicone surface of the device over time, so only water-based lubricants should be used. Avoid using the device alongside vaginal pessaries, topical antifungal creams, or other intravaginal treatments without first consulting your pharmacist or GP, as concurrent use may not be appropriate.

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