So I think that's a great answer. It's all about risk mitigation and tolerance. Your test tested if the part work to a reasonable and hopefully calculated level. It's good that the suppliers' management accepted fault, too. It's a lot harder when they don't but honestly in the professional world I've found that to be much rarer than consumer.

To me, and I'm not an investor, and probably not your target audience, those 3 short paragraphs told me a lot more in a positive way than I expected. I don't think it would be out of place to put it in the post. Honestly as is I thought this was your guys' fault for myriad reasons. Now I'm flipped the other way. Of course it's still your problem even though it's not your fault. Or, maybe, you do claim some blame for the worst case analysis not shaking out that edge case. Either way I feel much less like you guys just went to the hardware store, bought some random lube, packed the bearing, and shipped it thinking you'll figure it out on the next launch (which is sadly the fast and loose reputation new space is starting to get).
