PREPR Safety Can Opener 5 "Total satisfaction. No problem." Bryan 19 January 2017 I read the reviews before I ordered - and accepted the challenge! If the instructions are followed as written the lid is removed very easily and safely. Used correctly there is no problem whatsoever with this product. If customers are experiencing any difficulty then the fault lies entirely with them and not with the can opener. I have lived for over four score years and this is the best opener I have ever used. It has to be 5 stars.
