I am sorry, but this is a piece of junk. It worked ok for about four months and then became more and more difficult to use. After about nine months, it will barely open half of the can, and then you have a royal MESS at that point because now you have to figure out an alternative way to get the can open after half the top has released.
I love the concept, and if there were a manually-operated one available I would use. But the gears of the battery-operated one (we also went through batteries like crazy) wear very quickly (I doubt we averaged one can per day opened) and it just sits there and runs but will no longer pull itself to open the can. It is worthless now!
Bottom Line: No, I would not recommend this to a friend
