Query: OXO Baaaaaaad Grips(NO Grips)

I think this is THE worst kitchen helper I have ever purchased. It will slip off unexpectedly while you are trying unsuccessfully to unscrew a jar lid. I have come close to injuring myself a number of times, so will not use it any longer. I would give it a minus 5, actually, but that wasn't an option.I do not recommend this to anyone. It is easier to whack the lid with a butter knife and then smack it on the underside of the jar a few times...works for me, and hey, it's free!!!!!!
