Hornady rapid ar safe - Hornady RAPiD Safe AR Gunlocker

Bought this to allow me quick access to a shotgun and a place to keep my carry gun when I’m not able to carry yet out of the hands of unauthorized persons. I DID NOT buy it as a safe to keep thieves from stealing my guns. It opens quickly with either the tags or using the electronic key pad however is quite noisy when the lock opens. I’ve mounted it upright on the wall of my closet and am using lithium batteries however I haven’t had it long enough to say how long the batteries will last. So far it works well for my purpose and am pleased with it.
