content: I read the reviews prior to ordering, the color indicated in the photo was purple (which I really wanted) but I took note that several folks received red. I ordered anyway and of course received a red one. In spite of not getting a purple ball I still think it's a good product. Heavy duty, which was important to me since I need to "trust" my ball, as I too am heavy duty. It holds it's shape and it's volume of air and I feel very comfortable on it. I'm in a stability ball class and have tried the other balls there and like the weight and feel of my "red" ball. I'll probably order another smaller one, a 55cm. The 65cm is great for sitting but a little to large for some of the other activities so I think having a pair of different sizes is the way to go.
