Hello fellow commuters,

I was looking into Michelin's self sealing inner tube, the Protek Max (see link below). Has anyone used these before, or heard of any problems or design flaws?

Oh, and before you (rightfully) mention Joe's No Flats; I looked into purchasing them but unfortunately I can't find any with schrader valves (automotive) with the correct dimensions for my bike which is 700c x 38.
