Prompt delivery of a quality product at competetive prices. Fitting was straight forward and we completed all 4 locks in under 2 hours and I am a reluctant DIYer. With multiple locks it is worth getting the coloured fobs to distinguish between keys for doors. Locks all move smoothly and we feel more secure with the enhanced security features of these locks. We replaced one key/thumb turn, one dual key and a pair of patio door locks. All are of the same great quality and sit in the door funiture well. All in all a purchase I am very happy with.
