    I did have blow a tube due to a pinch when installing - my fault. But the tubes have been good. My only gripe is they seem to leak a little faster than my previous tubes. I find before each bicycle ride having to pump up the tires a little more than before.

    I was using these tubes almost exclusively for several years but noticed two consistent problems:

    1. When inflating them with my Blackburn floor pump, I'd have to attach the pump at least 3 or 4 times before getting a good seal. I'd get it attached, start pumping and hear it leaking out from around the stem. Sometimes I couldn't get it to seal at all on its own and had to hold pressure above the valve stem with one hand (or a foot) while trying to somehow pump with the other. It wasn't until I tried other brands of tubes that I realized the problem was with Q-Tubes, not the pump.

    2. The other problem occurred a couple of times out on the road with my Topeak RaceRocket pump. When unscrewing the pump head after inflation, it would also inadvertently unscrew the the removable valve core. Admittedly this is partially the fault of the pump, however it led to much cursing and the decision to buy tubes without removable valve cores.

    Since switching to Michelin tubes with non-removable cores, both problems have been solved.

    FWIW most of the 'Q-Tubes' I received were actually manufactured by Kenda.

                      I initially bought 700x35 ( 4 tubes ~$23) tubes but returned them for 700x32 due to new tire installation. paid $10 to return them!!!!
                      New tubes came, put them in the tire, started pumping air, at 30 psi the tube blasted!!!!
                      The tubes came in crumpled boxes which showed either they were not packaged well or they were ancient!
                      Never again these tubes!!!
                      total waste of money!

                        Only 200 miles or so thus far, but I have experienced no issues whatsover with these tubes. The paved roads in Maine are not cycling friendly, either!!!

                        I replaced the original tubes with these and filled them with green slime. The removable core is a great feature with these.
