I got 60 blanks and 340 prefilled. There were some manufacturing issues with the filled ones and those have already been returned and I'm waiting on the replacements.
I only tested 1 of the R4 it came back at 3.0Ω.
Overall I have loved all of the V2 revisions.
I have a better designed carto, just need $$$ to prototype and someone to sell it to.
