nice stable ball :-)

The color (green version) is really like in the photo; The ball looks first simply beautiful.
The first time you inflate he was just over 50 cm thick, the second attempt, I then made the 65 cm. From what I have read about other balls, this is normal at this AntiBurstSystem.
The material is pleasantly solid, but also not too hard (Inflating with the supplied pump works just fine for a normal woman). You sit elastic, yet somehow determined or secure. (For comparison, I had another ABS-ball of the same size, which has rather felt like a giant marshmallow and to be so now returned)
After a few days use, I have today forwarded again air and hope that the ball will keep well.
The only restriction, but for me now no penalty value: depending on the light you can see a couple of streaks in the material that might have arisen in the production process.
Otherwise: Super sitting experience and, indeed, what the eye :-)
