Best cost/quality ratio!
I initially used sunlu filaments to save monay, years ago, but spool after spool i saw this company to grow and to improve quality every day! I now use only sunlu for tpu, pla+ and petg for my Ender 3. I appreciate very much the costant performances, best cost/quality ratio end also the possibility to buy on different channels at best price. Hope they will extend filament variety also with special materials, as for standard once the service Is very good.
