Absolutely love the finished product installed.  Putting the units together where a bit challenging because the panels fit extremely tight together.  I had take the panels off on two of the three units to adjust cross bars.  Too, our application was a bit more difficult because of the slump rock mounting onto our house.  It was much easier to install the hood after the L-brackets are attached.  Being precise in measurements in the installation is critical.  All in all, love the transformation of the front of our home!   Would recommend the product.
