This exercise ball is definitely the best quality one I have ever used. It's extremely thick and durable. With the included hand pump it took me approximately 2.5 minutes with continuous pumping to fully inflate. The ball is a little bit smaller than I anticipated but I used the sizing suggestion from Live Infinitely and it fits me much better than other ones I have had. I am definitely on the heavier side but the ball supported my weight no problem. It's nice to be able to use as a desk chair too for balance. I would recommend this to anyone needing to work on posture, or flexibility. Get Here Amazon
