I have one and like it a lot. The big thing for me was the cost. Seemed like everybody else wanted double the money for some 1" tubing and sheet metal. It does rattle a little bit but I wrapped the part of the bracket that it sit on with a few layers of electrical tape and that took care of most of it. I'm sure most of the noise I here now is the tools in my tool bag. I never did trim down the sub box, I just let it sit on top of it. Even with tools, two bags of tire chains, a strap, and a few more odds and ends the sub box hasn't show any signs of distress. I wedged a folded up sponge between the rack and my sub box to fill in the slight gap.
