I bought and installed by myself while removing landlords cheap faucet. The old spray nozzle came out very hard, had to fortify myself with a cocktail. Once removed and cleaned like heck the new faucet with sprayer was a breeze. I noticed right away the flow & temp control was so very much improved. It looks great and I am so far 1 week in very pleased with the quality. I kept old faucet to replace when I move into my house in about 6 months, but I wasn't calling maintenance for ANYTHING, they're awful! Thank you for making an easy to install product.
