I'm pretty impressed with this can opener. It's ready for use right out of the box! I thought it only had a tiny plug at first, but it's really a retractable cord haha!  This is a great way to keep my countertop tidy and organized. The first can I tried to open with this was a short can, which didn't really work out for me. It wouldn't catch right and couldn't cut through the top easily. The next one I tried was a normal size can, and it cut perfectly!
