I discovered this gadget years ago. It always works for me although my Mum never got the hang of it.

I find large jars more difficult to open though as I have small hands. I find that the Boa can be used on larger jars if I turn them on their sides - it can be a bit messy then but you have a lot of control using the Boa and can give the lid enough of a turn to loosen it rather than take it off completely. For ring pulls, I always use a vegetable peeler which has a pointed but not sharp end and is 'V' shaped so it is strong but slips under the ring and lifts it gently. I agree that bleach bottles with their child-proof tops can also be granny-proof as well - some makes are better than others for ease of opening.
