/Powerful Motor/ Powered by 2*AA batteries (Not Included). Driven by the powerful motor, the Gear will guide the Blade to cut along the can (regular can ONLY; NO pressurized cans) rim. (Slide back the bottom cover to remove or install 2xAA alkaline or rechargeable batteries into the battery compartment according to the polarity (+/-) instruction. DO NOT mix and use used & new batteries!) /Hand Free Operation/ Good for disabled people or people with RSI or arthritis. Just one press of the Start Button and release. The automatic can opener will cut by itself in one go and will stop automatically after cutting. (The Max can size that can be fully cut in one go is 90mm (3.5) diameter. If the lid of a bigger can needs to be removed completely, press the Start Button again and let it go once it resumes cutting. And again, it will stop automatically after cutting.) /Easy to Reverse/ If jammed (low battery level or a deformed can rim), push and hold the black Reverse Button at the bottom rear down continuously to release the can. Keep the Reverse Switch depressed until the can opener stops; or use a 4 or 5 mm cross-head (or flat) screwdriver to turn the motor in a counter clockwise direction to release the can if batteries depleted. /Regular Cutting Edge/ The built-in magnet will hold and keep the lid stay with the opener when lift it off the can. The magnetic force (though little) is strong enough to absorb the light-weighted lid (handle with care when lifting). The regular cutting make it possible to use the lid again sealing the can. 24/7 Online Service!
