Review on Convenient One-Touch Electric Can Opener - 2 Pack, Assorted Color by Brenda Black

I would give this can opener five stars but one. It doesn't always work and I can't figure out what's going on. When it works it's awesome, but oh my god. We received two packs a few months ago and the one we opened worked fine until it broke yesterday and freshly charged batteries wouldn't move it. So I ripped out the second one and put it down and lo and behold it didn't work after it came right out of the box. I found the battery installation instructions to be a little vague, so I switched the battery installation back and forth - there are four permutations and none worked. What a disappointment. I've even tried (shuddering) alkaline batteries, but no joy. But wait. Tonight I decided to give it another try just for fun and today they both work - the same recharged batteries I couldn't get to work last night. Try each opener first tonight and they will work - find out. I have no idea what's going on. I looked at the one star reviews and found other people with the same experience, except they didn't come back later and tried again. I swear if I was superstitious I'd be terrified of can opener demons. Last note. In fact, we received two packages instead of one, which we really liked, but stopped working after a while. So I returned it for a refund and bought two packs for a few bucks more, thinking it would be worth it if we could get, say, a year of this. We really like this can opener when it decides to work. Now I'm wondering about can opener demons with the original. I have to say I am very happy with Revain's return policy with free shipping and a full refund. Very good.
