I bought this the other day and I wanted to leave a review for how the install was. Now, the mapping was off, slightly backwards but I was able to fix that (power cord placement wasn't right) but no big deal. I had to build a plug for the cord since the last range hood was wired. Once I did that (20 amp btw), I was able to pull the cord through the slot I made and held it. The hood is very light so I didn't have assistance, nor needed it. Once I set one screw in the hole, it held just fine. I screwed the rest in and tada! It was finished.
