I really like it
Color: Green, Color: Green
This thing is pretty cool. It's small, rechargeable, and it works in a weird way but very well. When I first tried it I thought it was broken and I ran it around a few times and it never cut the can where you see them cut with a normal can opener. I then realized that the whole top of the can lifts off! I've never seen that before. I actually really like it. So far I've only charged it once, but I don't use cans on a consistent basis so the charge will probably last forever. I just have to remember to plug it in occasionally so it's not dead one day when I really need it! The only reason it didn't get five stars is because the button is a little bit sensitive. If you're not careful sticking it in the drawer that button can press itself easy and then it will just run continuously.

This quit working exactly 31 days after delivery. Since the day of delivery counted as day 1, I am out of luck on my purchase.

Mixed results using this auto can opener...
Color: Green
I had high hopes for this can opener, but was let down. This can opener failed me half of the times I tried to use it. For some reason it wouldn't cut through the paper surrounding the cans. I tried it on small, medium and large cans. It worked best on larger cans. I got it because I liked the idea of opening cans without having to contend with the sharp lids that inevitably fall back into the opened cans. It is unsanitary at best and a safety hazard at worst. On the plus side it is rechargeable, so no battery worries there. It fits nicely in the hand for ease of use. It appears to be of sturdy construction, so it's a high quality item. And being small it will store easily. The price is right and it represents a good value for your hard earned dollars.
