I say I was lucky because 2 of the front doors were bulging worse than my original door. And one of the side panels had 2 of the plastic hooks broken off. The one front door that I ended up installing is warped a bit but it's better than the original was. So at least for Antec-US, I still stand by what I've said before.
Haha, almost exactly the same thing happend to me. I got replacements for my bulging side panels twice. All eight hooks of the first panels I received were broken. The second panels arrived with one hook broken.
I mailed them if they perhaps want to rethink their packaging for these items, and they said they would. In the same mail they asked whether I want a third replacement but I said no.
But when it comes to service speed and being "on the ball" you're right. No complaints regarding this.
