I have arthritis in my fingers and wrists, and can't open ring pull cans at all. As my new dog only likes tinned food I was really struggling to cope. This gadget has solved that problem for me, working well on large cans of dog food. It doesn't work for me on ring can tins of soup. You need quite a lot of strength to pull it towards you once the end is beneath the ring - which you also have to lever up first - and perhaps I lack that strength. Whatever the reason it won't work on soup, despite the illustration! So I like it, but it's not a complete success and the tip is quite thick and bulky.
