Query: Not easy to use - but looks cool

I bought one for my bf at the time, one for me. We both thought it looked awesome because it blended in with our other keys. alas, it is just about the worst bottle opener I've ever tried to use. The bottom part doesn't get a good hold of the cap of whatever you're trying to open, and then you start hurting yourself and it's just really inconvenient. usually it takes me 2-3 tries on different sections of the bottle cap to really get to my beer or whatever it is I'm drinking. but aesthetically it's awesome - I'll give it that.
