This is an OK can opener. It's nothing to write home about. I feel you need a degree in engineering just to get it to work. It’s tough to turn and is not arthitis friendly by any means. My hubby uses it and after he got the hang of it wasn't that bad. It does the job, kinda..just not the best can opener I’ve ever used. Very dissapointed. After about a month it was useless. Blade no longer sharp.
