Excellent product, exactly what I paid for. Little heavy for mounting on wall but you can do it. Make sure you have plenty support. I own a couple purchased someplace else. There ideal for securing networking and security equipment from burglars attempting to steal or damage it. At first I was skeptical this was strong enough to protect from crowbar or bat but its more than suffice.
I put only two 48 port switches in it so far, so I don't know how it performs when full, but it felt very solid while I put it together and I am not concerned that it is bend under any pressure I will subject it to in a calling center with 60 users. Be careful not to strip the screws when assembling the unit and you will have a very effective and inexpensive way to house rack mountable equipment.
