Not a great product

I guess you really do get what you pay for as i just received this product and the side screw railing is bent on the top a little but I'm hoping the amps can screw in around where it is bent. I also got two of the same sides resulting in the vents being the wrong way round on one side. Hoping once the amps are screwed in and the rack is in place that all these faults won't be noticed
