Got this because while traveling in south america i saw at a supermarket this nifty can opener with similar concept but much better than the one here. I am fed up with the standard can openers which have these rotating parts which cannot be properly cleaned/dissinfected.It is cheap. It might be used for emergency purposes. It is too small and bends out of shape after a few uses. I went to a local asian supermarket where i found a stronger can opener with non rotating parts (nor sharp parts for that matter, but works great somehow).
