Sugon 8650 arrived, what I can say, what a beast.
Internal built design is very good as for chinese manufacturer, probably it will work fine for years, if not distributor in Poland has huge spare parts inventory, f.e heater for 25 euro, whole handle with heater 50 euro, there is also the turbine, power supply pcb, front end pcb but I didnt asked the prices for them, i think they will not cost much.
Everything is excellent except the plastic chrome buttons, but I can live with that
