About 2 years old. Works great. Only small (under 1cm) black mark at the back from accidentally putting a metal bowl in it. I got a new microwave so I don't need this one anymore. Includes all the hardware for installing, etc. It is this model YWML55011HS https://www.whirlpool.ca/en_ca/kitchen/cooking/microwaves/over-the-range/p.1.1-cu.-ft.-low-profile-microwave-hood-combination.ywml55011hs.html
