This is a great product but when I received it, the product did not match the promo video and there were no instructions to install it. The video shows the Air Cannon hanging on the bracket in a horizontal position, but the mount is actually for vertical. After a while, I figured that out, and hung it up and is working out great. I would give this five stars, but the fact that the video didn’t match the product and the lack of instructions, I am giving it four stars. I also wanted to add that I had to move the locking wheels to different positions so that the Air Cannon would hang properly.
