CalExotics Duotone Balls - Ben Wa Kegel Exercise Weights for Women - Pelvic Floor Trainer - Purple & White Adult Intimate Toys - Perfect for Home Workouts & Sexual Wellness

My biggest complaint with these is that the string is like nylon. There are other products that are silicone with smaller or no seams.The cord on this one is porous, which invites bacteria to live there. It's extremely difficult to keep clean when compared to other Ben Wa balls out there. However, if you're looking for something to try, and already know how Ben Wa balls are suppose to work (I suggest researching or going to your local adult store and asking for info), and you're on a budget, this will not be horrible.I received my package yesterday and used them for about 20 minutes and they felt great I could actually feel them moving around and you will stay aroused the whole time they are inserted but the only thing I dont like is I bled after used them so thats why I gave them three starsPurchased this product for my wife so she could build some muscles and get some plesure which is what they are designed for. Cheap plastic, too large(size of a golf ball) and the string that attaches the two balls is noncoated nylon. She tried them inside her for 5 hours to give them and honest try but no plesure nor did she have to squeeze to keep them in. She said that she never even knew any thing was inside her hope this helps.i initially loved the product BUT noticed a yellowish brown fluid running from the seam of the ball while cleaning in the sink. It was coming from the seam BECAUSE IT IS NOT SEALED. i broke the outter plastic ball open and there was a metal ball inside that had rusted a bit, im assuming dueto fluids that had seeped through the seems. it just didnt strike me as safe enough to try again. Good Luck!!This product is fun, but not quite as pleasurable as I thought it would be. Darn 50 Shades! Maybe it'll be a little more exciting used with something else.They serve there purpose.I wish I could give this product zero stars or a corner of a star. Balls were attached by a nylon string which was not sealed were connected to balls also the seams of the balls themselves was very rough and not sealed meaning fluids can get inside of them were you cannot clean and you can give yourself a very nasty NASTY infection.Save yourself the time & money DO NOT BUY!This was my second try with this type of product. But my husband found these and ordered them for me. I put them in right away and the fun began. They were ok while just sitting but the car ride home was AWESOME. I was so ready by the time i got home. ;-)
