Does it leave sharp edges?
No - the SmoothEdge 3 cuts along the side of the can rim, not the top, so neither the lid nor the can is left with jagged or sharp metal. This side-cut design makes it safer than traditional top-cut openers, especially for seniors or children.
Is this can opener battery operated?
Yes. The Mueller portable can opener is powered by 4 AA alkaline batteries (not included). There's no cord to manage and no outlet needed. For best performance, always use fresh batteries - avoid mixing old and new batteries.
Is this can opener easy to use?
Yes - it's designed specifically for one-handed operation with no wrist strain required. Place it on the can rim, press the button to turn on and press again once it finishes cutting. It's one of the easiest can openers for limited hand mobility.
How does the magnet work?
Once the Can Opener finishes cutting around the can, its built-in magnet automatically grabs the lid and holds it securely when you lift the opener away. This means you never need to reach into the can or touch a cut lid with your fingers.
Does the magnet always lift the lid?
The magnet reliably lifts most standard round can lids. For larger, heavier, or sticky lids, our Can Opener has a built-in lid remover tool on the front to help gently pry the lid free. Both are practical design solutions for different can types.
