Had these for a few months. They were fine. But noticed after cleaning this week dirty water was coming out. Since I decided to order heavier ones I decided to break them open...they were disgusting completely rusted out now I'm going to the Dr to make sure there's no infection. Because you could tell they've been rusted for a while!!!

I've used this about 5 times and I didn't really feel anything unless I'm actually jumping around. I had to cut the string off because it was so uncomfortable. Then on the last use when I took them out black water started to come out of it because the seals aren't tight enough to keep water out. Get something completely sealed. Just spend the extra $5-10 on something better. I'm very disappointed ...I wasted money on this. I hope the stuff inside the balls don't cause an infection. Read more

The gap between the 2 balls is too big & ends up pinching

The plastic tubing holding the balls together and to pull it out is not flexible at all, and aren't sealed well, meaning that you have to really sanitize to be safe. The seam on the balls is very difficult to thoroughly clean. I tried them once and threw them out.

Pros: Easy to remove and put it. Cons: Wasn't beneficial to me nor had any effect the way they are supposed to. Not weighted enough
