Charge before use, have strong hands of you are going to use on someone other than your self , couples will enjoy
I've never used one of these before, but it's pretty cool! My chiropractor recommended that I get one to help loosen/relax the fascia on my abdomen and help my lymphatic system to move better. This ball is palm sized, not too heavy, and completely encased in silicone. There's a button on one side and a port on the other for the charger to go in (it looks closed up, but it's not). The button lights up when charging and when in use. There's an insert in the box with minimal instructions, and the ball has several different vibration settings. I didn't notice a whole lot of difference between them, except for the last one, which is more of a pulse. Still, it works quite well for massaging my abdomen, and it does seem to increase blood flow and get things moving.
This little sphere is simply amazing! This tool has helped with getting rid of the knots in all the hard to reach spots.
The ball is hard rubber which helps to release a tight muscle but the vibration helps more. I use it on muscles around my hips and it is very helpful.
