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 David Underberg

Ball arrived in a damaged box with no instructions for use. There is a bag with a "foot pump," 2 plugs, and a plug remover - mind you, this was all intuition on my part since there was no instructions included. The pump included is an absolute joke, I didn't even get one full pump of air in the ball before I gave up and used an electrical air pump, which filled it with no issue. I didn't know how much air to put in it without instructions, so I guessed. We'll see how it goes.
