Bought another of these after using up the spare I had lying around. Either the plastic goes somewhat yellow over time (likely) or the material's changed slightly between the two batches. Doesn't seem to have changed its mechanical properties though. I haven't had any problems with quality, and have only stripped them by crashing.
