Purchased this after moving into a student apartment once realizing no one thought to bring one. It was super cheap (less than 1$ I believe). You would think using a simple can opener wouldn't be an issue, but it actually took many tries to finally figure out that unlike every other can opener we had used, the handle had to be turned in the opposite direction (towards you) to move forward on the can! After mangling a few cans figuring this out, it eventually became second nature and worked like a charm.

Works great for the price, but heads up that they are made backwards!
