"Great opener, but poor longevity, found better substitute"
We bought this at a Villeroy & Bach factory outlet store for about $14 4 years ago. We loved it the whole time and it saw daily use, but it eventually stopped working because the teeth that turn the can failed. We went back to the outlet store to swap it for a working one and found the store was no more.

While we were at the outlet mall we went into a kitchen gadget store we found a "Good Cook" brand "safe-cut opener" (google for "good cook 11834") which is virtually identical (even same insignia on the wheel with teeth that wears out). The two big differences are that the can gripping comes from squeezing levers not force from turning opener (I think the better grip should reduce teeth slippage, reducing wear, making it last longer) and it was just $9.

"Worthless"
This is the worst can opener I have ever purchased. I was tired of the Dollar Store El Cheapos so I went out to buy the most expensive one I could find. Big mistake! You need to be a rocket scientist to figure out how to fit this to the can, and then a sumo wrestler to turn the knob!

"High price, low quality. Buy a Kuhn-Rikon."
Effective until it failed after 18 months of occasional use. No longer grips the can edge. No response from the company. $30 piece of junk. Save your receipt. You will need to make warranty claims. Not durable. Poor design. This opener grabs the can parallel to the can side. The Kuhn-Rikon opener is a much better choice: much less expensive, grabs the can perpendicular to the side, giving a tighter grip on the edge, better leverage.

"Doesn't last long - Buyers beware"
I purchased this product due to the reputation Rosle has and due to they warranty the product for life. Yet when the product failed I cannot seem to figure out how to get it replaced. The gears have stripped out making it impossible to use. My wife cut her hand really bad trying to open a can with it after it failed but she was determined to open the can but this didn't happen. I had to run her to the emergency room and on the way home we stopped and purchased a can open because who knows how long it will take to get Rosle to replace it. I have written emails to the company with no replies yet. As fast as this oriduct failed I believe Rosle will have to either have to correct their design or send me a new can opener annualy on a scheduled basis. When the product works it works well but the product quality is poor if the gears strip out in a years time.

"good for only a year"
The can opener worked well for the first year, but like a lot of people who have commented, it just stopped working. After a year, Amazon couldn't help. I emailed customer service several times through email at rosle and never got one response. So if you don't mind paying $30 for using a can opener occasionally for a year, this is your product. But for most of us, this just isn't reliable. A can opener is a pretty simple tool and there isn't a reason why it shouldn't "just work" all the time. So although I really liked it the first year, I am very disappointed with the product today. It won't open a can, it just spins in place and pretty much does nothing now and customer service from Rosle is non-existent. So poor value, poor reliability, poor craftsmanship (only lasted a year) and very poor service. i really wanted to like this product but it is nothing more than a paper weight now.
