I got a new vehicle, and missed the vault that had been in my husband’s truck. I am not mechanically inclined and was able to put it in myself in less than 30 minutes, including finding the tools. I love being able to lock up things when I need to, especially if I am on a work trip. The vault is not super big, but it fits a full size 9mm as well as a few other things. I went with the barrel key lock only as I looked on it as less to go wrong. Will definitely be getting another vault when I get another vehicle. The only downside I can see is that I lost a plug, as the vault only has 1 plug spot and my center console has 2, but since it is mostly just me in the car is not an issue as of yet.
