I bought this ball to replace a cheap one and wanted a good quality ball that would take regular use by 2 heavy people. This certainly fits the bill. It is the same quality my gym had and I really liked the fact that it came with a tape that you put through the nozzle of the pump so that you know exactly what size it is. I found the listing confusing as to whether there was a pump included but wasn't that bothered whether there was or not. When it came there was a pump in the box, not the best one in the world and I would suggest that pumping the ball up would make a good work out in itself but if you follow the instructions and partially inflate the ball and then leave it overnight and finish inflating it there is no problem. The ball has not leaked nearly as much air as cheaper ones do when under use and as a disabled person I have absolute faith in this ball being safe while with a cheap one I have worried in the past that it could go bang if subjected to a sudden shock. I really don't think there is anything to worry about in this one. I would buy this again if I needed another one and would recommend it to others who want good quality, non slip surface, safe ball with no gimmicks.
