I call this my little kitchen robot, because he does the work of opening cans pretty much all by himself. Just attach him to a can, press down and watch him go!
Isn't that fun? I could open cans all day long! There is an old-fashioned hand-operated can opener in my utensil drawer, but the beauty of this little guy is that he'll still open cans even if the power is out, for quite some time before he runs out of steam. Over time, I'm sure he'll need to be plugged in more often, but so far he's needed charging about once a month. The cutting lever is removable for easy cleaning, too.
My little kitchen robot came from Walmart: you can learn more about the product here. I'm sure it is available for purchase at many stores, but I found it at Target and on Amazon as well. Walmart does have the best price on it. This post was not sponsored by any of the companies mentioned, nor was I paid by anyone for my opinion.
