Firstly the ball itself is very sturdy and well built. My hamster loved it. The stand however at first didnt fit with the ball very well, i bent it so that it had a better grip however it broke off.. I sent an email to the seller and revieved one back very very quickly saying a replacement stand was on the way.
Overall its the ball you are paying for and the ball is fantastic, im also sure that the replacement stand will be beter.
