Question: Can this safe be mounted to the side of the desk or does it have to be underneath? I guess the question is can it go both horizontal and vertical?
Document: To my surprise and chagrin, I received the Hide Away Universal Mounting Bracket, which is too large for use with the Desk Mate. I called Dean Safe Company and they exchanged the one I received for one that fit the Desk Mate. Unfortunately, I paid the price for the Hide Away bracket.I like my Desk Mate Keyless Security Box. It is substantial and secure.
Was on the fence about this stlye or a gun vault electronic. Since this is my bed side gun safe I would hate to have a electronic malfunction; slim chance though. The case is tough in design. It will keep unwanted hands out. NOT A GUN SAFE. Mine is a bit hidden and that helps with being secure. Wish it was a bit cheaper, but the quaility is great and the locking mechanism is great and easy to use
I have had a closet wall safe by V-Line for 10 years. The advantage of the V-Line safe is that there are no batteries to go bad. I had an issue setting the new code and had to call their support which was excellent.Some years ago a burglar tried to get into my wall safe. He even found the keys (wall safe has two barrel locks in addition to push buttons)  He could not get into it.
Just be aware you would have to spend additional money to get the extra bracket.Anyway, it seems like a very secure way to keep the kids from the gun. I have two quibbles with the safe. I use it to store a full size Smith and Wesson 1911 in there and it is slightly too big for the safe. The beavertail of the gun pokes out just enough to keep the door from closing if I lay the gun on the left side which is the position I would prefer it in.
Like I said I have it under my nightstand and wanted it to be stealthy so what I did was to take black duct tape and try to cover up as much of the gold bits as possible. Looks pretty ghetto but hey at least it's harder to see. Without the tape you eyes go right to the safe. With the duct tape it just looks like a shadow under the night stand.All in all, a fantastic little safe for a handgun. I can't recommend it highly enough.
You have to realize the safe is kind small. The hinge is very nice and welded on one side to deter one from trying to punch out the pin. It comes with only the mount that you see on top of the unit. There are two thumbscrews you can unscrew from the inside of the safe to detach it from the mount and take the safe with you. The Universal mount bracket DOES NOT come with it. The picture is misleading. This means you can only mount it to an under surface.
The box itself is sturdy. Size internally is accurate to the picture. I really like the mechanical lock. Easy to use and reliable so far.The mounting mechanism is probably fine if you're mounting it under a shelf or desk. The instructions also indicate you can mount vertically/sideways. If you do so, this thing is a pain to get installed correctly.
If you don't know the V-Line system and you put in a bad set of pushes you can try for the rest of your life and will never be able to open it.This safe is easy to secure to a wall, floor our any where else and while I guess you could with time pry it loose that still does not get you into the safe. With power equipment you can open the safe but the drop in burglar will not have that much time to work on it.
The V-line Desk mate is a nice box.The lock works flawless and the box is well built and very sturdy.The reason for 4 stars instead of 5 is because I would like to see the removable tray have a strap of some sort to pull the tray out  a bit when the door is opened. Also, the tray could use a little more of a positive stop to keep it from coming all the way out too easily.Very good box overall. Buy with confidence.
From the Amazon web site, I searched for pistol safes and found the V-Line Desk Mate Keyless Security Box. I was confused by the photo accompanying the written description of the Desk Mate Box. The photo is a V-Line Hide Away Keyless Security Box. The Hide Away box is larger than the Desk Mate. From the photo, I was expecting to receive the larger security box. I did receive the Desk Mate, which is a great security box, but not as large as expected.
