I’ve only had it installed for a few days now, so YMMV and time will ultimately tell though upon tinkering around after install I already feel greater peace of mind. Installation was a breeze, used an oscillating multi-tool to cut through drywall quick and easy and then its just bolting it down to studs. If you are planning to conceal it with a picture or something make sure to look up the dimensions of the outer lip edge (believe its 17″x15″) I kinda goofed and had a picture picked out only to find it was not quite gonna cover it, an easy fix though. Love the locking mechanism, super simple to set and very secure.
Reliable and sturdy product. No pesky batteries or digital scan that might fail in your time of need. The mechanical lock works like a charm and likely open for 100 years with no needed maintenance. The install was easy, with dimensions that will fit all standard 2X4 studs set 16″ apart. American made product that will likely outlive its owner.
