I doubt many have purchased 2 bumpers to compare side-by-side, thus the silence.

I will simply offer that I have yet to find a single OER part that was worth very much more than its weight in scrap...

But I admit I haven't tried their body panels. Mostly talking about trim pieces, rubber/plastic parts, springs, misc bits and goodies like that. Many 100% worthless, others can be made to work with creative trimming/adjusting/messing around, so only 60% worthless. So frankly I find myself running from that OER brand whenever possible.
