The faucet and functionality are awesome.  I installed it myself and it was relatively easy (I'm somewhat handy).  I will say the instructions could be a little clearer.  For example, one of the steps says to put the O-ring on the faucet bottom but there were three different rings included so I wasn't sure which to use without doing a little research first.  A page identifying all the parts included would have eliminated that confusion making for an even simpler install.

I only installed it two day ago but I'm very happy with my purchase.
