Our review
Place it on top of the can, press the button, and it drives itself around the rim and cuts the whole lid off in a few seconds — no squeezing, no twisting, no fighting a stubborn manual opener. It cuts along the side seam so the edge comes away smooth rather than jagged, which is the detail that actually makes it safer, and it's a genuine help for anyone with arthritis or weak grip. It runs on 4 AA batteries (not included).
With over 119,000 ratings it's wildly popular at 4.2 stars, but I'll be straight about the spread. The most common complaint is reliability out of the box: some units just hum and won't cut, or stop working after a few weeks to a couple of years. It's common enough that the 1-star reviews cluster around it. The redeeming feature, echoed again and again, is Kitchen Mama's customer service — people who got a dud report a fast, free replacement that then works for years. So: a brilliant tool when you get a good one, with a real-enough defect rate that you should test it early and use the warranty if needed.

FAQ
Is the cut edge safe to touch?
Yes — it cuts along the side seam, leaving a smooth rounded edge rather than a sharp jagged one.
Why would it just hum and not cut?
That's the most common defect — try fresh AA batteries first, and if it still won't cut, use the warranty; Kitchen Mama is known for fast free replacements.
What batteries does it take?
4 AA alkaline batteries, which aren't included; rechargeable AAs work well too.
Does it fit all can sizes?
It handles most standard round cans; very small or oddly shaped cans can be trickier to seat.
