I purchased this Delta faucet to replace a similar Delta (faucet) that had completely worn out after 15 years of use. I had to hire someone to install it & he said it was really easy. I love the sprayer especially as the last one had also gone kaput. The only complaint I have about this faucet is that it doesn't turn off completely with ease. Normally, you depress the handle & the water stops completely. With this one, it stays on at a small stream stage unless you depress it again, sometimes up to 3 times. 

If I had any way to know before now & if not already installed, I'd take it back for an upgrade. It looks really nice, however. The cut off issue is only an inconvenience. It doesn't affect it's functioning at all, so I'm giving it a good review. Good value faucet, but I suggest going up abit in quality if you are installing it yourself.
