Input:
I have gone through so many can openers over the years.  I keep them clean, I keep them dry, I don't use them as weapons.  However, after a few months, they get cranky, and in less then a year, they stop working all together, and I have to get a new one.  I've tried cheap ones, and even some pricey ones, and they're all the same.  So far, this OXO can opener has lasted the longest.  It's outlasted all of them, and has not even started getting difficult yet.  I'm very excited.  Time will ultimately tell, but I can say this is the best one I've owned so far.
