I ordered around 12 discs and they were all boxed nicely but 2 P Model S duraflex glow discs were warped. In over 70 discs I’ve never received a warped disc like this. One was so bad that it was at least 1/4 inch off the surface on two sides! The other wasn’t as bad. But yikes where is the quality control? This couldn’t have been during shipping as they were both packed amongst other discs. I didn’t bother G3T about them and I’m hoping I can flatten them out as it’s not worth sending them back. My order included a P Model US base plastic and it was fine. The other Duraflex glow discs were also fine.
