The only issue I had was finding two studs that were actually 16 on center to mount the box between. Taking time to work with the 'Stud Finder' to get exact positioning is important. Also, be sure not install close to an electrical outlet as wire could be attached to the studs. Once the sheet rock is cut out, the rest is fairly quick.
Pros: well made, nice lock design
Cons: could hold maybe 4 guns
