***** Update: I wanted to add that Kitchen Mama’s customer service was genuinely great. They followed up, honored the warranty, and sent me a replacement even though I couldn’t provide photos at the time. The replacement works perfectly and the experience was way less stressful than I expected. **** Original Review: I just needed a simple electric can opener because I have crippling pain in my hands and I can't use a manual one. I didn't expect anything fancy but for the one job this thing had it still really let me down. This thing is so slow it reminds me of my AOL days. And when it's done, it just... keeps going. When you turn it off it takes FOREVER to wind down. The first few times I tried yanking it off because I thought it was stuck. And then it fully died in under a year. But honestly maybe what bothers me the most of all is when I contacted customer support about the warranty replacement, I got an email back asking for photographic proof that my BATTERIES WERE IN CORRECTLY. Really? (A photo that I could not provide because it had broken days earlier and I threw it in the trash, who hoards broken appliances?). I really expected better from a ‘reputable’ brand.

Great opener

Color: Blue

Had a battery operated can opener before and was always changing the batteries. Love the safety cut and this works great now that I can just charge it with my phone charger. Fits in my drawer so no counter space used
