Today I got the photos from my contact at the factory and the finish on the EpicGrips was indeed a show-stopper. You can see how the edge rounding is nowhere near the nice bevel on the samples. I am so glad this was caught before they shipped.
I'm not sure how they could fix this in just a week, but that is what I have been told so far. I will make an official update on Saturday, with whatever I learn between now and then.
Meanwhile, I just want to thank everyone for the unanimously positive feedback. Your continued support really keeps me full of the energy I need to tackle this thing with full force. You guys are the best!
