I bought this to replace a mechanical S&G lock on my safe. The quality of S&G has really gone down. This is the cheapest feeling lock you can imagine. The faceplate is very thin and light plastic that feels like a cheap toy. When I slid the battery door back to install the battery, it immediately broke off with very minimal pressure. I then used the provided screws to attach the faceplate to the front of the safe. First of all, it just loosely snaps into place. Second, once snapped onto the bolts, it has a lot of play and moves around instead of sitting securely against the safe door. I emailed security center about the lock but never got a reply. Disappointing
