“Update #2: Just received my second ball and here's what I've noticed: it came direct from China and seemed a little inferior in quality. Not sure how it will hold up. I will complain to TRAKK because I chose the "order again" option but after receiving it I realize that it was fulfilled by a third party vendor rather than TRAKK who fulfilled the first order. Therefore make sure you look at who's fulfilling the order. My second ball did not say Pro-Tec either. It just came in a plain plastic bag.Update: 3 months of pretty regular and intense use for foot massage and this ball hasn't deformed, popped open or lost its shape. I stand on it regularly with full body weight and it's holding up just fine.I've ordered another because it's excellent for foot acupressure.Earlier review: I used this for the first time just now after receiving it and my impression is that it's perfect for a great foot massage. It's flexible but gives just enough to make the massage deep but not painful. If you like a good, deep massage this ball is just right. The knobs are firm but not painful. Time will tell how this will hold up and if the seam opens. If that happens I'll post an update. For now my feet are deeply grateful and relaxed ðŸÂ»��”
“I like it, but had a hard time using it by myself & can't stand against a wall for as long as I need it to work out kinks & pain. Otherwise this is a very good product & it will last a long time.”
