Note on proper use: 1) Use all new (4 new batteries required) high quality AA batteries, preferably Duracell, Energizer, or AmazonBasics. Cheaper less quality new batteries are inadequate and may not preform as necessary. 2) After completely revolving around the can and cutting the edge, the can will still appear to be sealed. After prying up the lid will it be evident that the can and its resealable lid are detached. 3) When soiled after use, wipe down blade with damp cloth and dry. 4) Do not lift or forcefully remove the can opener from the can while it is operational. Forceful removal can cause damage to the knife-edge.
