The door handle and knob set is made very well and beautiful. The hardware and product overall are of solid quality. The deadbolt lock and knob/thumb latch have good spring action. For installation purposes the only issue I had was there is no latch included where the Knob/thumb latch come together inside the door. You will need to buy it separately.
