This little gem is a must have in any kitchen! I purchased this several years ago. After getting it home and seeing how truly amazing it is I promptly purchased another one! Yes it's that good! I cook daily and use to struggle with opening cans of all sizes even with electric opener . That no longer is an issue. Just clip it on any size can and press. It goes around the can for you then automatically stops when completed with the lid firmly attached to the powerful magnet. It is totally hands free allowing me to do other things while it does it's thing. Fits the hand comfortably, releases easily, top comes off for easy clean, leaves smooth edges and so much more. I love that it is chargeable which means no cord and easy to take along on picnics, camping, on long road trips or wherever you may need an opener. I absolutely LOVE this product!!
