Well built unit bought as a replacement for an older similar unit. Unit was well packaged but the metal washer to secure the faucet was too narrow in diameter. The copper supply line could have been an extra three inches. No ferrule or nut was included with the product. After unpacking the new unit, a trip to the plumbing was required to purchase a roll of 1/4 inch copper tubing plus a brass ferrule and brass nut.
