Pros: They give you a buffer plate to protect packages from the studs when they get dropped in. Anchors might be a nice touch, but too small for a bottom anchor. good for rear anchor. Combo lock is ok, but needs to be high up on door in order to see number. A lot lower in cost that other all metal boxes. This price range would normally get you a very small box or a cheap plastic one. Cons: Lock is too flimsy for roadside mount, so I added a hasp and padlock. Rear holes should be knockouts, so I had to plug them to keep water out. Fit and finish is a little loose, so I ran silicone seal over all the seams just in case. Should have plug for bottom holes if back holes are used. Had to cut buffer plate down to cover bottom anchors, as it is built to cover the rear mount anchors. Maybe a two piece buffer plate? If not then it would really help if they stamped the pattern into the plate so you know where to cut and bend. I had to wing it. Having a plastic drill template for the anchor holes would be really nice too. It's a little short for USPS boxes, so I had to use a 6 inch concrete pad instead of a 4 inch pad to elevate.
