Good machining, no chips when flushing it with water. Stays cool with even a minimal water flow. A brass heater block is delivered with it so high temperatures are possible. A lot of spares like bolts, spring washers, a fan, silicone sock and extra square nuts. There are a couple problems however, the spring tension can not be adjusted and the tensioning lever can not be moved completely without colliding with the hose (Last picture). The filament can still be inserted fine. The technical drawing by the seller is bit strange but you can basically just use the same mounting as the hemera/matrix extruders.
Very good extruder. Perfect cooling. I was able to reduce retraction. Also I get no more clogs when printing with higher chamber temperatures.
