Does anyone have this??? Well, I ordered three of them, was hoping they would keep my poor fingers from being stabbed time after time, pfffttt, didn't work. They are one size fits all and very narrow in size. I couldn't get it to work for me, somehow the little nub thingy on the top of it gets in the way. Seems to me, it would be a whole lot better if that weren't there, although, maybe it's me and I'm just not using it the way it's intended. What do you all think????
