First off I love how this toy has a velvety touch, but when inserting it kind of hurts and drags in the skin. Anyways I only used these for a small period, simply because they broke shortly afterwards. So the quality is kinda crappy. I really don't have much to say about these. I think you can find way better kegel excersises on edenfantasys than theses.

However, they are waterproof of course and about 4 1/2 inches long when inserted into the vagina. They also have a retrieval cord, which is nice. They can be washed with regular soap and water. Be careful cause a lot of hair and dust can stick to these.

When you walk they do vibrate in side of you when hit together, the friction and movement will do this as you wear them throughout the day. This felt fantastic while they lasted. There was a clear film that came off when I made the mistake of bleaching them when I had gotten YI.

You can use a waterbased lubricant with these, I wouldn't use oil or silicone as this could possibly damage these if purchased. I wish mine did last longer, because you seriously can't beat the price withe these but unfortunately they are cheap and poorly made.

Bottom line, I don't have much to say and I don't recommend them. But if your on a tight budget and want to try kegel balls they'd be absolutely great for beginners. After I tried these I ordered the Fun Fantory kegel balls which I highly recommend, and there more sturdy since there silicone. These Ben Wa Balls are crap.

Please be warned as I previously mentioned, If you get an infection while using these don't bleach them in a bleach solution. They will damage and erode the material. I'd definitely recommend you looking for a sturdier kegel balls.

Mine broke, but they felt great and gave me a full feeling.
