Review on Spectre Performance 4668 Locking Header by Mike Johnston

I must have a bad batch. 4 of the 8 I've installed so far had an offset hex head which made it appear like it wobbled when I screwed it in. Then all the holes had to be drilled because metal burrs prevented the security cable from going in. Dissatisfied. I don't want to negotiate for a refund as the Amazon Landing is so far away.
