I think he publicly addressed the first time it was brought up on SST and said he changed the material in his filters to prevent the filter strands from breaking through. Something along the lines.. I've only ordered from him since after that and I inspect my vials and haven't hit any issues yet.
@OP are these older batch vials or newer batch?
The very first floater found in primo gso was batch c105
The batch of NPP GSO that had floaters was c105
The batch of NPP MCT that had floaters was c110
I can check the test E batch# when I get home.
