I don't usually yell in my reviews, but this opener is outstanding!
Opens cans with half the effort of all my prior, and more expensive, can openers.
I've tried all different types (including the "no sharp edges" side-openers), and this is better by far.
Pros:
1) Less effort required to turn handle
2) Does not spin the can (which can mar countertops) -- instead it travels around the can
3) Leaves the inside of the can very smooth - helps food slide out and it's safer to reach inside the can
4) Does not leave any sharp edges around the top of the can (unlike some side-openers)
5) Works great with cans of ANY size
6) Takes up far less drawer space compared to a typical can opener (great for camping too!)

Cons:
1) The edge of the lid might be sharp (but it will fit nicely back inside the can once it's empty)
2) Might take a couple tries to get the hang of how to properly remove it after opening the can
3) Does not include bottle-opening or can-piercing attachments on the device, as typical openers do

This opener is fantastic for what it does. If you want something with bells & whistles, look elsewhere. But if you want something that simply opens cans all day and all night, this is the one you want.

I have had just one hand for 44 years, this can opener is the most sturdy and easiest to use can opener I have ever used.

It's small, its durable, it clicks right on the can, nice design.

It works, doesn't hurt my hand, opens every can every time. We've been through so many can openers that we'd given up and turned to his old fashioned c-rats opener. This opener is superb. Works like the c'rats but better!!

This is the best can opener I've ever owned, and well worth the price.

For whatever reason, it seems to be hard to find a quality can opener today. After a period of months to years (depending on quality), something always breaks, loses traction or goes out of alignment. I can't tell you how many openers I've gone through over the years.

After a handle on my most recent "standard" opener broke, I decided to see if so could break the cycle. I set out to find something better, and this is what I settled on. It has not disappointed. It's essentially solid steel, so I can't imagine how I'll ever break it. It cuts easily, so turning the crank isn't difficult. The lack of handles seems odd at first if you're used to the more common can opener design, and don't entirely grasp how this one works. But handles aren't necessary"”which means fewer parts to break.

Don't let the unfamiliar mechanism intimidate you. It's simple to use. Just set the opener on the rim of the can and start turning the crank; the blade automatically digs into the can and starts cutting. Easy peasy.

If you're tired of buying can openers every few years, and are looking for the one that'll last for the rest of your life, this may be it.

I see some reviewers complaining about rust. It's not stainless steel, so yes, it can rust. It will require a little bit of care, like any carbon steel kitchen tool. If you're someone who insists that all your tools be dishwasher-safe and require near zero-care, and you're not willing to tolerate a little rust, you may be disappointed. I personally don't mind investing a little (very little) effort to maintain a good tool.
