Being a contractor I have been a Delta guy for quite a few years. I installed the faucet to the sink and then installed the sink to the counter.  What I like about this is the easy install with the water supply hook up. Took about a half hour. Once hooked up I ran it thought some tests.  I like the flow of water and the water spotting on the finish really worked. I like the action on the handles nice and smooth. As always with Delta if you need parts like a cartridge they have it.
