very  pleased with the purchase. the product arrived early as expected. it comes in a white box with all part included including the escutcheon. I decided to install it by myself instead of calling plumber and it was not that complicated at all.  i just have to squeeze myself on the bottom of my sink to remove the old one, but other than that that it was not  that hard. It comes with 3/8 compression connector then you have to buy a 1/2 adapter from home depot. most old houses have 1/2 compression connector.  the price of the product is cheaper than other DIY stores.
