I purchased this set last year for my much better half and myself. I, in all my mildly obsessive compulsive glory, bought this in the hopes that we would not have keys thrown willy nilly on the counter tops. I measured twice before installing them, and we haven't had a single problem in all these months. The finish on the key holders still looks as good as then day they were put up. Aside from my wife's initial attempts to put her keys in the male holder (I think she may have been attempting to assert her dominance) we have had not issues. Also, I must personally admit to laughing (at least once a week) at the fact that the locks are located in the groin. This I see as a plus because, honestly, who doesn't like to laugh.
To sum up: if you want a functional key holder, that is also an attractive addition to your home, buy these. Also, if you are slightly immature, and enjoy mumbling the word "giggity" to yourself every time you hang up your wife's keys, buy these.
