I asked Rado to look at my front door to replace the existing old deadbolt and lock with a new keyless entry system.... was a very delicate install as the door he was installing it on was mirrored. he installed the lock .. but it was defective... had to wait for a new warranty replacement unit. Rado came back .. removed the damaged unit and reinstalled the new unit. He had to programme the new unit which was difficult because the instructions provided were inadequate. He was very fast... knew his stuff, didn’t damage the mirrored door.. which was very difficult. He was pleasant, efficient and went out of his way to make it a good experience. Would highly recommend his service.
