I bought one in 1998 and it finally stopped working a couple of months ago. The Achilles heel are the wires from the combo pad to the batteries. I pulled a little harder than usual to get the pack out and on installation it just stopped. Gunvault's warranty is for 1 year and they have since changed hands and won't work on the older models. Their advice, " get a new one." I will probably get a different one with the Medex locks. No batteries to change and they always work. I'd like to get a "shotloc" but it's $160 beans-a little spendy but has quick access.
