I am always skeptical of buying and using new (to me) filament especially from a brand that is also new to me. I bought this spool, and when I received it (fairly quickly too!) I unwrapped it and put it in my AMS. I saw nothing that said anything about making sure I dried it out before using, so I began using it straight out the wrapper. Once installed, my program and printer both gave me warnings of using this type filament in my AMS system. The filament is VERY stiff and brittle so it could break off inside the AMS..... I continued to print a tool that all other filaments failed at under pressure. When my tool began printing with this filament, I watched very carefully, ready to jump at the first stringing, warping, etc.... I was printing this tool at 100% infill, so I knew it would take a while to complete. From start to finish, there were NO issues or problems AT ALL. No breakage, no spaghetti, no warpage - NOTHING! SO absolutely happy with the results of this filament. I sure hope it continues to the end of the spool!
