Question: Will it open #10 cans?
Document: At first it was good, but the blade got dull quick! I was going over the can 3 or 4 times, and sometimes that wasn't enough to cut the lid off. I have simple metal can openers that are 10 years old that open cans better than this, and on the first go around.
I should return this. It just doesn't work on most cans. It doesn't seem to work by going just once, around twice is usually needed and then getting it apart is difficult. I called up the manufacturer and they said that it doesn't open #10 cans. Really I have no idea what a #10 can is, but it doesn't even always open a standard can that soup, vegetables etc comes in. So what use is it?
As can openers go, this is a pricey model and yet it only lasted a year or perhaps 100 cans. The metal gear that cuts through the edge of the can lid is worn out. Even when new, the handle was relatively hard to turn and took about 8-10 turns to open an average-sized can. That makes for a sore hand after 4 or 5 cans!
About 5% of cans I encounter are still impossible to open this way, and I have to pull out my ugly, rusty, falling apart "traditional" opener to complete the task.10 minutes to open a can? Memorizing which brands use glue? No way! I will donate this gizmo to some unlucky person, and will buy the "traditional" OXO can opener. Do yourself a favor and follow suit.
Through my two years of constant use, I have found that the opener does not always open cans quickly and consistently. It works like a charm for some cans - one round of cutting and you are done. Yet for some cans you need to cut a few rounds to open the lids. Frustratingly, quite often (maybe 1 or 2 times out of 10) you just can not open the lids regardless of how many rounds of cutting you apply.
Only works on certain cans, and certainly not the big #10 cans either. It did work on some and the smooth edge is nice. Sent mine back.
Because the lip is thicker on the large cans, I had to go around twice in some cases. I have always loved Good Grips and was so thrilled to move up from my less expensive, trusty original Good Grips $10 can opener. My recommendation? Just buy the cheaper one and save your knuckles. Between the hassle of a harder crank and the difficulty of use - it just isn't worth the trouble.
Ordered this because i was tired of buying the $6 variety which would break after 3 months. In a nutshell-  I spent quite a bit more and ended up with something that didn't work 9 out of 10 times. Works adequately (at best) on standard cans, but anything a little larger or a little smaller requires a 360 degree rotation up to 10 times to get it opened. This opener is perfect for someone wishing for just a little more stress in their life.
How much can you say about a can opener. This is my second one, wore the first one out after about 10 years. The old style would get food trapped in the cutter head and then into the gripping gear and unless you cleaned it well after each use, the thing would be loaded with bacteria. The lids would sometimes fall into the food and any bacterial or dirt on the lid was now in the food. You could use the lid and inside edge of the cans as a skinning knife.
i have the pampered chief but these are easier  especially with my hands cramping all the time and the arthritis the knob is larger so it turns little for a lot around on can and of course no sharp sides with it cutting the side of the can  great buy too about $10 cheaper than the other brand
Answer: yes...size of can would not matter....after you complete a revolution of the opener you might not think the can opened...there is no distinct click...plus this opener cuts right under the lid, not thru it...so just work the lid a little after and you'll find it opens cans 'different'...but very nice
