Product review (3 stars): Nice product, but be prepared for what you get
The good - it matched the Broan range hood exactly,  nice quality (it is sheet steel, but nice guage).

The bad - it wasn't well packaged -- the first one was shipped back before it ever arrived.  The 2nd one arrived safely (thank FedEx).  That said -- there were still a few imperfections at the bottom (which I put at the bottom of the install).

The ugly - first, I have done quite a bit of home improvement -- but the install was frustrating.  No instructions (not that you need them, right?) ... but the one side had a plastic protective coating that I almost missed that can be removed.  But the worst part was ... with the four screws -- the sheet did not lay flat on our wall.  Instructions could have explained what I found on the internet... use construction adhesive if needed to flatten the install (I used a light amount and smoothed it out with a wide putty knife.

Conclusion - I would buy it again -- but Broan could do more to help the install go easier.
