After some minor difficulty installing, the faucet is in and I love it!  The only complaint is that the counterweight keeps getting hung up on other lines under the sink and so to return the sprayer to its proper position I need to go below and free it.  Otherwise, it looks great and the stream of water is strong.  I have bought other makes of this type of faucet and sometimes the stream is anemic.  Not so with this one!  As for longevity, I cannot comment as it was installed five days ago.
