Very durable, but a little hard to inflate, only because the the cap is hard to screw on before air gets out

It did seem to lose a little

The only con I have is that the cooler in the center between the two seats, when its completely full of air, drinks and ice and your sitting in the tube (which sinks a little from your body weight) its too high for you to see the person you sharing the tube with!

The only complaint is that when I sit in the floatie, it caves a little in the middle, enough so that my Michelob Ultra cans will fall out of the side cup holders, a minor nit.

These are the sturdiest, most comfortable, and convienent tubes I've ever used
