This exercise ball is perfect for me because I work in an office so I have a lot of time to use it while not interrupting my work. It is very sturdy and the " light show" is so nice, and my kids love to watch the lights! My 8 year old son is even able to use it so that shows just how easy it really is to use. Its entertainment and exercise all in one device! Its definitely worth the price to get thr benefits of building up your muscle and entertaining yourself and others at the same time and it requires no batteries, nothing but your own power and strength. Definitely a stress reliever as well!!!
