I was very impressed with the great packaging for shipping, quality of the morrow and the amount of hardware and wonderful directions included! I also watched the video recommended and it really helped! I had a couple “snags” that were totally my issue with the install (an exhaust pipe behind my middle spacer making it impossible to screw ot in). Thank goodness this was such a great product and had a lot of other support spacers so I could work around the behind the wall problem! 
Thank you!
