Don't buy this if you're not handy with tools. To install the batteries, the instructions say to do it while the GV is on it's bottom. The battery pack is inside at the rear on the top. Removing the screws on each end is easy. Then the strap that holds the batteries comes off. When putting the pack back, you have to hold the strap up against the pack, align the holes on the strap, then hold it up while you replace the screws. You have to do all this with one hand! There is only enough room for one hand. I put the GV upside down so gravity would hold it down while inserting the screws on the bolts. After two hours, I gave up and I just laid the pack down inside the GV. The knock out for the cable could not be knocked out. I had to drill the knock out out. Then when I attempted to put the nut on the cable end inside the GV, I cut my hand on a sharp edge of the GV in the front. I could not get the screw on. I had to drill another hole further back so I had enough room for my hand to screw on the screw and not get cut again. Note: If you pull the gun out on the padding, be careful to lift the gun up, off the bottom. If you don't, the gun will be scraped as it goes over the door hinge, which is not covered with foam, on the bottom. If you are going to mount the GV, you'll need a right angle or stubby screw driver. The supplied screws are 1 1/2" long. There is very little room for a screw driver. Including mounting the vault on a shelf, it took over 3 hours to do all this.
Pros: Strong, will meet my needs.
Cons: Set up is terrible.
