The first faucet we received was defective. It may a very loud noise when turned on and if you tried to use the sprayer only about 1/2 the water would come out of the sprayer and the other half remained coming out of the other faucet.
We attempted to contact manufacturer and never heard back. I notified Wayfair and they sent a replacement faucet (5 stars to Wayfair customer service!)

The second faucet is much better than the first, however it occasionally makes the same sound and the faucet still has a small stream of water running when you use the sprayer. 

We hired a plumber for the install so it was quite a waste of money to have to have it installed again. Disappointed with the quality of product.
