You've dodged my first question twice, so I am going to assume that if GB units ship with the same ano flaws that Merlin's unit had, you won't be offering refunds.
It's disappointing that the screw issue wasn't addressed at all - the concerns were regarding longevity and durability, not function during a single build stream, so the fact that you "didn't find anything wrong with it" is not reassuring at all.
And yes, I understand that this is a hobby of preference, but I am not asking questions about preference here. I am asking questions about the quality of a product you're selling for $450. There's nobody out there who prefers screws that crack after half a dozen re-builds, or ano with large chips in it.
