Mich had convinced the good reviews and I had ordered me this ball. I wanted this ball for Pilates and gymnastic exercises and I have but now bought another ball (the one we use in the course). This one I did not like: 1. The ball has stuck appalling! This is the ball is not entirely smooth makes sense yes and must be so, but that was a really nasty feeling to touch the ball and touching the skin. Why that was so, I do not know if that was ever used by someone else and sent back or if these balls are so. Anyway, that's when my present not as extreme, and especially not so unpleasant on the skin. 2. The ball smelled very unpleasant! That was uncomfortable. 3. The ball had extreme crease marks and stripes in the material that are not gone, if you have drawn on material. 4. A small Ballpumpe I would find better. Younger supplied straw I personally find something unhygienic.
