Fast delivery, 8 days. However, the product itself is not great. First, a threaded insert had melted plastic up into its threads, preventing a screw to go in. I had to scrape it with fine tweezers under a microscope. Second, it seems the arm brackets are bent sideways. That cause their holes to not align with the ones on the main part. I just can't screw them on. Third, the provided switch rocks sideways, which is not great for z-height and calibration precision. There is too much play in the holes (or the provided screws are slightly too small?). Fourth, if I fit a real E3D V6 hotend in it, the heater block touch the part cooling fan duct. I don't see how that will not lead to melting it... Also, you can put a silicon sock on it. No space for that. Fifth, not all screws go into a threaded insert or a nut. Some of them bite directly into the plastic. Especially the one holding the hotend with a spring. Ultimately the plastic will get loose.
