KFFKFF Half Balance Trainer, 23" Stability Ball, Supports up to 660lbs, Includes Yoga Ball, Resistance Bands & Pump for Comprehensive Home Gym Workouts, Blue

Grandson loves it, especially the color. Since his favorite color is blue. The price was very reasonable.

The balance ball is very high quality. It feels very stable even when standing on it at 160 lbs. We all love it.

I have used this in part of my physical therapy for an ankle injury. It works very well.

Great for working on balance. Use it for golf, and overall maintenance.

Great!! Can't beat the price either and it's just as good as the pricier brands!

Because I use the flat side of the ball to do one legged standing running man. I noticed that the depth of the air plug hole is 3 inches across. This makes it not so perfect for me to center my foot and balance on the flat side. It's mainly what I wanted it for! The more expensive Bosu ball has a smaller plug hole.

I had trouble finding the plugs to hold in the air. I had to use my electric air pump, the pump that came with it is worthless. There weren't instructions that explained details about the air plug and pump.

The plastic base lacks rigidity, bowing out when inflated, lifting the rubber feet off the floor, making it slide if not ~ 50 lb of down downward pressure put on the ball patt. And the "flat" plastic side doesn't provide a flat surface to stand on when the inflated ball part is down, so your are standing on a rounded convex surface. The included pump was useless. I used a ball pump that I had that has a wedge like attachment for blowing up Bosu %26 Swiss balls.

The ball area has more of a point than the normal shape for some balance training. Upside down works well

The pump does not work, and the plug to stop air from leaking also doesn't work.
