It is robust and easy to grip. Inflation has claimed only a few minutes time. If the ball loses its bounce, I need a few pump strokes to bring it to the desired voltage.
A product that I would buy again at any time and can recommend with a clear conscience.
He is also particularly good for inflatable toys (beach balls, swords made of rubber and similar toys. This is so simple that even makes my 5-year-old son and has this great fun.
