I mean, I can clearly tell it prints VERY well even with a minor speed increase, I made a few small things with it and the quality of the finished product was very satisfactory. Definitely not quiet by any stretch of the imagination, but my workshop is in the basement. Close the door and it's all set. Doesn't bother me upstairs at all. My dog slept next to it and considering I finished the build at 11:30 pm I fell asleep next to it as well in my desk chair.Don't be intimidated by the build. Took me an hour or so going slow and safe.All in all, considering the price I paid and the quality of the prints, I can say I'm fairly impressed. Here's to many models in the future to work with my Tronxy X5SA-400 3D printer.
