here are my impressions so far with SeaCans PLA 1.75mm filament. Diameter is not very consistent on the spool. I get some voids or under extrusion also lots of over extrusion. I have experimented with diameter values in slic3r and found that i needed to create a setup for each colour. its really only an issue on detailed small sized prints. i.e. figurines.
Extrusion temperature varies from colour to colour for best results the range i have found is 190C to 205C.
Also I find the filament very brittle compared to other PLA filaments used.
