Review on Get Fit with ATIVAFIT Balance Ball Half Trainer: Inflatable Yoga Ball with Resistance Bands, Pump - Supports up to 660 lbs for Home Gym Workouts, Core Strength and Fitness. by Jerry Leon

When I first bought the product, I loved using it, but I noticed that it would slowly lose air over a month of use. I thought it was the little plastic plug, so after the 3rd time, I tried putting a piece of tape over the hole after plugging it.The problem wasnt fixed. It turns out there's a hole in the side where they put a screw in and the more I used it / blew it up, the worse the problem got. Now i have a useless product after only 6 months of owning it. I thought I was buying a product made to last. The material is good, but the way they made it isn't.
