The essentials
Fun Factory Smartball Uno: what you need to know before you buy
Is it for you?
Who the Fun Factory Smartball Uno is for, and who it isn't for
It suits you if…
- You want a one-piece Kegel ball that's 5 cm long and weighs 40 g.
- You want to wear it while you move around, with an inner weight that rolls.
- You have a shorter vaginal canal: the manufacturer designs it with that in mind.
- You prefer to take it out by pulling a silicone loop.
Better look elsewhere if…
- You're looking for a toy for anal use. The manufacturer warns that this one isn't suitable.
- You want a slimmer one. The B Swish Bfit Classic Flex comes in sizes 2.9 and 3.6 cm wide.
Size and measurements
Fun Factory Smartball Uno size: as long as an AA battery
It's 5 cm (2 in) long, the same as an AA battery, and 3.8 cm (1.5 in) at its widest, a little less than a table tennis ball. It weighs 40 g, a little less than two AA batteries. The ball goes in and the loop stays outside for taking it out; the manufacturer doesn't publish how long the loop is.

Step by step
How to use the Fun Factory Smartball Uno
- Wash it before first use and put a little water-based lubricant on the tip.
- Insert it into the vagina tapered end first, until only the loop stays outside.
- Keep it in while you move: the ball inside shifts with every movement.
- If you like, alternate between squeezing and releasing your muscles while you wear it, as the manufacturer suggests.
- To take it out, pull the silicone loop gently.
Cleaning
Wash it before and after each use and dry it well, including the loop. Store it dry and apart from other toys.
Our tips
- It's for vaginal use only: the manufacturer warns that it isn't suitable for anal use.
- Use a water-based lubricant. A silicone-based one can damage the silicone surface.
- If you feel pain or discomfort, take it out.
- If you're pregnant, have just given birth or have pelvic floor discomfort, talk to your gynaecologist or physiotherapist first.
- Don't use it if you see cracks or the loop is damaged.
