I understand the disappointment. I had to return a blue anodized Launch, and a limited edition G-10 Ti-Lite, the first week I received them.
Buy a different color Endura, and send your other in for repair. You need more than one Endura anyhow. The new one will be in by the end of the week. I recommend orange and blue. I use cheapo torx sets, but I make sure I have the right size the first time, press down really hard, and go VERY SLOWLY watching closely to see if the screw is actually turning. I move my clips to the lanyard hole side, and don't mess with them again. I think the Tenacious series are the only ones that I have stripped.
