    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 bought this tube for my brothers fixie bike. He's only ridden the bike a couple times since installing the new tube, so we don't know yet how well it'll keep from being punctured. Did have an issue with the bulging out of the tire I when inflating. Specifically by the stem area:/

            Just regular tubes that do the job. All have been good out of the box with no defects that would make them non-functioning. The valve cores are removable, so make sure the core is tight so that it doesn't blow out.
