The listing asks that you select between 8-8.5mm and 8.5-9mm which I think are standard range categories?
But I do agree with the apprehension with an unknown brand.
Stumbled across this seller: Pearlesant.com
But don't see them mentioned as a seller in the forums. Anyone heard of them/have experience with them?
Based on the website would you trust them or is it better to go with a tried and true like Pearl Paradise...
