Functions VERY well.  The only thing I notice is that the gear/cutting mechanism - while sturdy in appearance - is not quite as heavy and robust appearing as our very old Swing-A-Way can opener.  This is NOT to imply that it seems cheaply made - it does not.  The biggest difference is that the teeth designed to grip the can are smaller, and spaced closer together.  But so far, that does not seem to interfere with operation.  I just have a bit of concern that the life of this device won't be as long as the much older one that had much deeper can-gripper teeth, so even as they gradually wore down, there was still plenty left to keep from slipping on the can.  View the rating as a very strong 4-star review.
