This is a great piece of hardware. I use it for larger prints mainly in Reflow PETG in our SATWARE//LABS. It performs very well and keeps the temperatures at the same level throughout the print. Stringing does occur in very small amounts so I'm a very happy customer. The direct drive extruder handles large spools (4,5kg) exceptionally well. This kit came with everything needed for my daily needs, even 3 different nozzle sizes were included.
