I have always been impressed by literally everything about Scalarworks. Their products are awesome, their website and descriptions are extremely well done, and even their packaging and included tools are first class.
A year or so ago, I bought a Kahles 1-6 and a Scalarworks mount from a forum member. Great optic and mount! When I recently went to mount an offset RMR, I realize that my mount was an older version, that doesn't support the offset optic. Scalarworks offered to switch it out for a new one that did, even though it was bought second hand -- I am literally blown away by how great their customer services is.
