I don't have a problem with certain friends trying to hook me up with people. I mean, if they have good taste, then I'm going to assume they know what kind of people I like and will know who'd be good for me. Other friends... not so much!
I got a wave when they did that "free wave!" thing a while back. It really didn't do much for me. The little wash pads didn't foam at ALL and they got hella stuck to the little wave thing and still won't come completely off. I'm glad I didn't shell out any money for it but maybe they've improved since the freebees or something.
