I consider the Zyliss Easican Electronic Can Opener a "must-have" for my kitchen.  I have arthritis in my hands/wrists which makes using a manual can opener very hard.  This can opener is so easy to use.  I just place the opener on top of the can and press the button.  It works quickly and efficiently to open the can.  At the end of the cycle, the opener pulls the lid off as I lift it off the can and it leaves no sharp edges.  I cannot express how much I love this opener!  Great for anyone, and a perfect appliance if you have trouble turning a manual can opener.  Highly recommend!
