As with most things these days, the instructions were in picture form only so a little unclear. The magnet that holds the lid of a can is not adjustable to hold smaller cans. I   Have only been using hand can openers for the past 25 years, so not sure if the lid should be as jagged after being opened or not: I do like the cord storage feature and the fact that you can remove and clean the top of the opener where the blade is. Also the extra opener included for bottles, etc is handy, especially for flipping the lever up on those cans you don’t need an opener on. I have not had the opportunity to try the plastic cutter yet. Overall, I’d say this was just a normal opener .
