This faucet was hard to find. Only Wayfair had anything close to it. It was delivered on time and was as it appeared in the ad. After it was installed, however, it leaked. I called customer service while my plumber was still there. Customer service told me that such leaks happen occasionally and that I probably just needed to remove the cartridge and seat, and then replace them making sure the seat is inserted flush. My plumber did that and the leak was fixed. I'd give customer service 5 stars. I give the product 4 stars because I think better care should be taken at the factory with pre-asembly to ensure that the product is not shipped with internal parts not properly inserted/seated.
