Excellent, if you are ready to be a little involved
The building is well organised, no parts missing and very clear instructions. The design shows no flaws, some parts were upgraded (f.i. the pulleys)
Initially there is a little bit of tuning to perform, however it makes you knowledgeable to run it at its best. The quality of prints is very good. Many easy DIY options can be fitted at a reasonable cost (dual extruder, heating bed, lights..). The parts are industry standard which is really helping and there is a great community around this printer.
Software : the provided CURA slicer is excellent even if I invested into Simplify3D.
