Info about THIS opener at the end.INFO NOT ABOUT THIS OPENER: Our first product years ago (store bought), very similar, lasted a long time. We called it the cockroach because it quivered and danced around the can as it opened it...but did the job well.INFO NOT ABOUT THIS OPENER: After it finally gave up the ghost, we purchased another one just like it. Didn't work at all (factory 2nd?), no way to know.INFO NOT ABOUT THIS OPENER: Recently we purchased one of the shorter models and it would get locked onto the can, requiring pushing the reverse underneath...send it back. With that one I discovered there are two types of battery operated openers which you place on top of the can. This one opens by cutting the side of the can just below the ridge. What that does is make creating messes due to can flexibility. Not a good design.INFO NOT ABOUT THIS OPENER: We also went through several plug-in openers; all of which tend to walk off the can ridge, requiring repositioning, and sometimes simply cannot do the job at all.THIS OPENER >>> Then we bought this one. GREAT CHOICE!!! (No I don't work for the company, wasn't paid for a review, and am not associated with them in any way.) Like our first one, it opens the can along the ridge, but appears to use a newer technology which works extremely well, quietly, no quivering, etc. This model opens by cutting the ridge, leaving the rigid ridge in place for can stability. The cut was clean and complete, allowing the magnet to pick up the lid perfectly! — IT WORKS BETTER (so far) THAN ANY CAN OPENER OF ANY KIND I'VE EVER USED AT 75 YEARS OLD (including plug-in, battery-operated and manual openers). DEFINITELY BUY THIS IS YOU WANT EASE AND EFFICIENCY WITH LESS LIKELIHOOD OF MESSES. Now the question which hopefully will take years to determine, is how long it will last. But it's cheap to replace!!! Having can openers be hard to work with and get a clean complete opening job is a nightmare. This one helped immensely. Hey, we still call it the cockroach like our first one, even though it is too well-mannered to hold that title.Love that it fits in a drawer and not on my counter taking up space. It works great for cans of all sizes. I do wish it would stop once the opening is complete but for the price, it works.My best purchase from Amazon! This is so easy to use and perfect for those with weakened hands, fingers, grip. Just lay it on top of can and push the button. When you hear the motor change to a slower speed and it has gone the whole way around, just push the button again to stop it. It's amazing how it cuts the lid off but there's no sharp edges! Can't figure out how it does that! At first I didn't think it had cut the can at all, but then realized I could just lift the top off. The only thing that doesn't work is the magnet to lift the lid off when you remove the appliance from the top. No problem though, for me. I feel the magnet needs to be sticking out a little more to grip the metal lid. All in all, this is the best thing since sliced bread!!Not as heavy duty as I'd thought. But works for soup, vegetable, meat cans.I've tried a dozen times on a small can of crab meat. No success! Is there a secret to placing it on the can??? Very frustrating since I have no other opener handy.Its pricy and tricky if you dont know how it works Once you do you wish you had it sooner!Look at the cilinder part and the cog. The edge if the can has to be pinched between them.Is NORMAL on some cans that the small end of the opener lifts up.The noise is little loud and the tool is a little slow but in my experience it left no sharp edges or shreds.You might need to pull the newly formed lid if the metal is heavier than usual.You put the opener on the can lid and press the button once. It might lift the small end of it and will move around the can, then the noise changes and you click again and is doneVery easy to use. Battery operated small in size big in production. Great product for senior citizen. I made a video but couldn't postI didn't know how.Opens can well. But the auto cut off feature on previous model was great. This one will just keep going until you push button to stop.This can opener works well, you might think the lid hasn't come off, but it's because the lid stays on until you take it off, so it appears to not have cut into it. There was only one case where the can opener didn't grab the lid on a can of chick peas, but if you press the can opener against the lid it is cutting, it will cut it fine. I am really happy with it, and would buy it for family and friends if they needed one. I have had it about a 2 month I think.Dislike, useless, hard to contact manufacturer for replacement, no email to contact since its in China. Called Amazon several times to solve this issue, asked me to contact manufacturer!!!!!Does not work on most cans, worst product I have ever purchased on Amazon.Als ich den Dosenöffner bestellt habe, war ich kritisch. Beim Auspacken und erstem Ausprobieren konnte ich feststellen, dass diese Lösung hervorragend ist. Der Dosenöffner öffnet per Fingertipp sauber wirklich jede Dose. Und das nur mit Batteriebetrieb. Respekt!J’ai acheté 2 ouvre boîte et l’un des deux ne fonctionne déjà plus, il fait un bruit bizarre et assourdissant. J’AIMERAIS BIEN QU’IL ME SOIT REMPLACE CAR C’EST UN PRODUIT TRÈS DISPENDIEUX. C’est dommage car il est facile à utiliser et securitaireJe voudrais bien un remboursement l’appareil a fonctionné à peine 8 mois.J’ai fait des demandes et je n’ai jamais eu de retour de contact avec le vendeur. DÉCEVANT.
