Mag was second hand? If so certainly that takes away QC questions from this particular case.
Mag was second hand - and is still getting replaced by RED? That's appropriate customer service/standing behind the product.
THAT is unbelievable service! The warranty would have gone away, with resale, of course and RED still replaced it. Just for giggles, I wonder how old the mag is?
One thing that might come from this, though, would be a revised warranty policy-term,etc..
Thank you very much
