Informative and helpful

There was a lot of information on the site to help you decide what you needed and in my case the size of gym ball I required for my son. I got the pump they recommended too as I have seen a lot of bad reviews on various sites, for pumps that come included in the price of cheaper balls, The sit n gym gymball seems very durable and robust, inflated easily with the faster blaster dual action pump and a week later seems to be holding it's pressure without problems having been used every day.
