As far as electrical can openers go, the Presto 05651 UTC model is a winner.  Overall, customers rate it way above average at about 4.7 out of 5 stars, citing that it outlasts many other electrical can openers by years, and that it is versatile in that it also sharpens knives and opens jars, not just cans.  It has the added bonus of a kitchen clock/timer that is displayed prominently on the front of it that can be used when cooking, as it is mounted under a counter in the kitchen. Other models of presto can openers also rate well among consumers.
