I've never heard of them and ran across them. The reviews are favorable, and the highest micron compares to 8000g.
They seem fairly inexpensive, and I could see them being useful for many projects.
I just ordered some and after I try them out I will post my experience
Had a hell of a time finding someone to ship to Alaska but Fordam did flat rate usps
Well I received the papers and cut them into smaller pieces so they would be manageable.
Tried them out wet on acrylic at a slow speed, just like Micro Mesh and these guys worked just like Micro Mesh! Final decision is for the price difference I'll be using the 3m from now on!
