I use my Tapplock on my gun safes (yes, plural). I have one mounted in my car for use when transporting my firearms and one at home, where I keep my “home security gun”. The home safe needs to be secure, but easy-access for me and my wife (only) in the case of a break-in or other emergency. The Tapplock serves that purpose PERFECTLY! We have the piece-of-mind that our gun is always locked away, but ready and available if we need it at a moment’s notice. In the case of extreme stress situations, or where turning on lights are not recommended, our Tapplock One is the perfect answer!
