The hardest part of installation was preparation of a solid mounting surface in the ceiling. Not sure why the mounting kit included drywall anchors ... it needs to be mounted to solid wood with very sturdy screws. I vented through the roof and that also took a good deal of preparation and a separate roof vent. I built a simple "table" out of scrap wood that I set on the counter top, straddling the stove top. Two people could then left the hood to the table top and with shims adjust it to exactly the right height to fasten the frame screws. It would be very difficult to do this any other way unless you have at least three people. The hood itself works very well but it is loud and vibrates slightly at the highest setting which I have never found a reason to actually use. The unit came with LED lights that I had to substitute for the original small halogens. I like the LEDs much better. It looks great! The glass seems to create more of an "open" feeling in our relatively small kitchen.
