I have this ball shell actually ordered a Pezziball order more comfortable to sit in front of computers. To understand why the ball rind is not well suited, I have to state the following: I thought the dish one would perhaps less "juggling" to maintain the correct sitting position. However, it rarely succeeds "get" immediately the correct position to the ball. Since the ball is made of good anti-slip material, slides or he turns difficult on the ground, as the pants to the ball. Then I took the 75cm-ball because of my size, I'll be sitting not very good with his feet under the table , You have to be based with both hands on the ball, so that squeezing and at the same time, the ball rolling under the table, sit on. Smaller people will probably have fewer problems with a 65er or 55er ball. I finally sit in the right position at the keyboard, but everything is perfect.
If you have previously placed the ball shell with the ball, it is impossible or at least much more difficult to bring down as just described in the correct sitting position.
I have the shell anyway given 5 stars because the ball rolled uncontrollably without them across the room. You would not believe how easily such a ball starts rolling. A small breeze in passing already enough.
