Let me start by saying this bracket is a solid piece of hardware. The cold-rolled steel construction feels substantial in your hands, and that powder coating gives it a nice finished look. I used it to mount my 12,000 BTU mini-split, and it hasn't budged an inch - even during some pretty intense storms.
The installation was straightforward... if you have concrete walls. Like several reviewers mentioned, the included masonry bolts work great for concrete, but wood stud installation requires some creativity. I ended up using lag screws into the studs after carefully measuring everything twice.
One thing that surprised me was how rigid the mounting points are. Unlike some adjustable brackets I've used before, these have fixed spacing between mounting holes. This became a challenge in my older home where the stud spacing didn't match perfectly. I had to add some horizontal support beams to make it work right.
The bracket does exactly what it promises in terms of protection. My AC unit sits about 8 inches off the ground, safely above snow piles in winter and away from ground debris year-round. After two seasons, there's no visible rust or wear - that powder coating really holds up.
For the price, you're getting serious value if your installation situation matches what this bracket is designed for. Just be prepared to possibly need some additional materials if you're not mounting to concrete. It's not the most versatile bracket out there, but for straightforward installations, it's rock solid.
