Input:
I highly recommend this can opener. I've owned it for 4 months. It operates smoothly and easily. No straining.  I don't like electric can openers because they get nasty fast, very unsanitary.  I prefer to toss this one into the dishwasher. I'm assured a clean and sanitary opener every time. I actually came here to buy a couple more.
