Bought this in 2014.  It cuts with little effort, and still works with minimal effort on my arthritic hands BUT..no matter how I've tried to con this thing into not letting the lid slide into the open can or how slow I approach the last bit of lid to be cut, it leaves a nasty snag ALWAYS and so you have to pry the lid out of the can, grab it and twist it to break the "snag" it leaves.  I've managed to decorate myself and the wall behind my counter with tomato sauce more than once.  And I've managed to cut my hands so many times, I lost count.
