AMD bumpers

Has anyone installed an AMD rear bumper? How did it fit? My car came with some cheap aftermarket bumper and it was warped in the middle, like there was a 2 inch gap in between the filler and the bumper in the middle and it was pinched at the corners. I actually dinged my paint a little. So I took it off and pushed on the center, and CRACK!! The bumper broke in 2 pieces, and this is steel!! So I got online and started looking and ordered a brand new AMD rear bumper cause it says that it is the closest to original on the market. I just want to see if there is a fitment problem on these bumpers or not.
