We love this faucet! Our old faucet never sprayed right and it got worse and worse. It's been so so nice to have the powerful spray feature in addition to and separate from the regular stream faucet. The spray nozzle is easy to grip, move around, and is long enough to reach most areas of the sink quite well. It will make a noticeable whoosh sound from the rush of water to the fixture - this happens when you turn the water on full blast and pull the trigger on the sprayer. It's less obvious when it's not on full blast. So keep that it mind - the sprayer is powerful but not quiet. The stream faucet is like any other faucet and works very well. I like the aerator on it - the water flows really nicely and comes out quickly to fill pitchers, bowls, and large pots.
I installed the unit myself and it was very straightforward. Over time, after swiveling the two different parts, the whole fixture began swiveling some (i.e. it loosened). I tightened it and it worked okay for awhile, but the swiveling persisted. It was more of a nuisance than anything - it still worked great. We recently had a plumber come to install a new garbage disposal and had him look at the faucet while he was here. He tightened it up (probably with a more powerful plumber's wrench that I don't have), and it's back to perfect. He told us it may loosen again over time, but as long as there are no leaks (which there are not), then it's just fine.
Still highly recommend! Great price, too.
