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.

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.

Hands Free Operation; Safe Cutting
Color: Green
I used to have a manual (as in turn-the-crank) side-cutting can opener really liked it. It eventually wore out and I had relegated myself to the standard hand-crank top-cut version that often left a sharp lid and sometimes a little burr or sharp point where the cut wasn't complete and the you had to the tear/bend the lid off. With this mostly hands-free Side Cut Can Opener, sharp edges will be few, if any. I say "mostly hands-free" because you do have to position the opener on the can and push the button to start it and, when it finishes, you have to push the button again to tell it to stop. On the demo can in my video, the lip was such that the cut was right through that edge such that there were no sharp edges. It is possible that some cans may be designed such that the cutter falls below that rim and cuts the can edge in a way that leaves dull lid but a sharp can. These should be rare, but good to watch out for in case you get one. Always assume edges are sharp until you verify otherwise. You'll note in my video that the lid was a little difficult to remove. Some of that may be learning curve with this new opener, and some it may be that is just how it is! I accept that and choose to move forward using this new, safer can opener. Recommended.
