I bought this with the Liberty's Centurion 12, along with the electrical outlet kit for the safe. installation was simple, easy to follow instructions. I bought this for ease of use and no worries. It works as advertised, I have a simple wireless humidity/temp thermometer and for over a year now it has done just fine. All items are kept at an adequate temperature and humidity. The rod does get slightly warm to touch, but nothing to be concerned. I keep steel, wood, brass, and electronics in the safe, and everything is good as new.
