It's about 3 years that I buy materials (mainly PLA+ and Resin, recently also some PETG) from Sunlu.The materials are quite good, I never had any problems with the resin.The PLA+ is a bit more tricky (it depends on the color) as it requires some fine tuning to print properly but this is absolutely not related to the quality, it's something that would happen with any brand.Also the shipping is really fast, in a matter of a couple of days I have my materials, it's on par with the shipping time from a non-prime Amazon.I totally recommend the materials from Sunlu. The only negative thing I can say, is regarding the website which is a bit... chaotic but nothing critical.
