I haven't tried their handgun safes, but did have the Shotlock shotgun lock from them for a while so we could keep the shotgun loaded in the bedroom closet without worry of little ones getting at it.
I don't have any reason to think it's common with them but the lock broke after very little use. I went to open it one day and the knob you turn after entering the simplex combination just spun freely. I was eventually able to get it open by pushing (very) hard on the knob while turning it, so I didn't have to throw a cutting wheel on my angle grinder to get the shotgun out, at least. It wouldn't have been a good thing to have happen had I been in severe need of getting the shotgun out of the lock.
I called them about it, they would have fixed/replaced it for me, but since I got it at Costco they suggested just returning it there and getting a new one. I returned it, but haven't gotten a new one yet.
