My TouCan has worked as described on occasion, but 85% of the time, it would go around the can a dozen times and not remove the lid.
But the very worst part is that while it is trying to cut the can open, it actually produces tiny metal splinters along the way. Needless to say, the times it has managed to open a can, I have then been afraid to use the contents, because it might have deposited a splinter into the contents.
Now it sits in the box, never to be used again.
Bottom Line: No, I would not recommend this to a friend
