800 miles, Valve Spring broken = engine toast
That is entire basis of my argument. If they were the vendors own springs and they failed, ok stuff happens. If they were ADVERTISED as rebranded Chinese springs than its buyer-beware. NEITHER OF THOSE IS THE SCENARIO.
The OP just said the packaging looks the same as the chinese springs he sees on eBay, but that doesn't mean it didn't come from the same plant manufactured to a different spec/quality requirement than the PEP springs. That doesn't mean that the ebay vendor and CoSpeed don't use the same boxes to ship springs in either.
My point is that there are still a lot of unanswered questions; too many to start grabbing pitchforks and lighting torches. We haven't even heard the other side of the story yet.
As a moderator you have engaged in slander and libel here, you may want to reconsider what you say in the future.

I think the Chinese springs are made mostly of bamboo shoots and rice.
And if the vendor doesn't choose to post up their side of the story, how is that anyone in this threads fault?
**Obviously, BTR springs are not Chinese springs, just in case anyone again missed that we're talking about a hypotheictal scenario.**
The main problem I see is that it's being assumed that they are the same exact Chinese PEP springs sold on ebay, without the consideration that it may just be that they come from the same place, but manufactured to a higher standard. I am not saying that is the case, but again, another hypothetical scenario to present judgments are made.
Notice the portion in bold. You poised a hypothetical scenario where BTR sold Chinese springs, but it was ok since it would be built to their specs but in the very next sentence, you criticize another vendor for selling Chinese springs.

The second Spintron testing was performed last December. We saw some issues with a LS7 and a LSA applications that we wanted to test. What we found is the 120 gram LSA intake valve is difficult to control and had a lot of bounce, and is a good application for something like the Comp conical springs, and the LS7 has a rocker/stand deflection issue which we fixed by redesigning the LS7 cam lobes.
We have good resources and we do a lot of testing.
