Almost perfect
In general I think this is a really well built printer from a mechanical perspective. The right and left nozzle calibration system along with the bed 'leveling' works flawlessly and is brilliant from a UI perspective. If you are printing PLA hitting real speeds of 250mm/s will result in near-flawless prints. My biggest gripe is related to the filament path into the extruder. The 90degree bend is highly problematic in that it creates unnecessary friction and frequently results in filament breakage near the bend. The hotends work well enough, though I have had issues with contact resistance to the PT100 sensor - this resulted in blockages due to a too low-extrusion temperature. Overall very happy with the printer especially with regard to printing PETG with PLA support material. This may not be a good first printer - I think some previous printing experience will help.
