Decided to replace my original door locks to boost security due to the rise in lock snap type offences. Picked this one as it offered the highest level of security. The price is reasonable and well worth the extra few pounds. The quality is excellent, it fits snugly into the door and the keys fit perfectly. The lock functions as it should. It was really easy to fit, I found removing the handles the easiest way to do this but it only takes a few minutes to complete. I measured my old lock and managed to get this almost flush with the handle as my old one sat proud by about 7mm. Overall a great lock to give some peace of mind.
