There's no quality control. Not only did the installer put in a permanent face plate totally crooked on the inside wall, but the outside wall coverings (where he drilled holes) are not flush and are messily caulked with piles of caulk (which is likely to disintegrate soon).
He left piles of sawdust and debris on the floor and didn't even consider cleaning up after himself. He left furniture moved away from the walls and didn't even consider moving it back.
He gave absolutely no instruction on how to use the equipment. After much frustration, we had to call their customer service and found out one of the remotes is defective and needs to be replaced.
