Bests & Worsts Reviews from Amazon

...intentional rip off? There is no 50 minute work out DVD included. The pump included does not work (after pumping air for 20 minutes straight doesn't even put a dent on the deflated ball) and becomes very hot after a while. I kept thinking the plastic pump is going to melt before the ball enflates (if ever). The "65cm" ball turns out to be only "55cm." I don't know... seems like a rip off to me, but amazon is not at fault, since the Nautlius web site has the exact same description for the item. Quality-wise, the TKO Cory Everson Fitness Ball 55cm I got a while back was so much better. The plastic isn't so sticky, and it felt a lot more durable than the Nautlius one, too.
