I love my Goodlife exercise ball! I luckily got my large one at a discounted price as most places mark these up really high. It does not deflate on me and when I sit on it, I don't feel like I am going to pop it if I put all my weight on it. Great product!

I love the Goodlife Fitness Exercise balls. They are a good brand but are still a very reasonable price, infact I think it was one of the cheapest ones at Canadian Tire. The ball is comfortable to sit on, bounces well and the air stays in for a long time. But just in case the ball is even sold with its own pump. Great for exercises as well as pregnancy pain management and bouncing a fussy baby!
