the bottom ring is too low to hold the ball properly
the pump has no fixed domicile
for a short time, particularly on the ring, a somewhat unpleasant smell

Conclusion
The exercise ball "workout ball" by Sportastisch the ideal seating for a good position in Office or at home is for people with a height up to 175 cm. As sports equipment can score the ball, because he appeals to many muscle groups and also provides for a healthier back. The resistance bands are great to provide more support for the training and additional training of the arms and shoulders. In this context, also the ring makes sense, I can recommend otherwise but not completely, because he's holding the ball at practice, due to the low height, not really. If you leave the ball inflated enough the supplied pump. If you want to use the ball but only off and on again and again have to pump him up, I would advise to buy a better pump. For people with posture or back injuries, which is "workout ball" a sensible purchase.
