Feedback from a customer:
I understand these are used items sold at a deep discount. But they arrived with heater cartridge and thermistor caked into the heater block, covered with plastic goo. Had the heater cartridge wires weren’t cut right at the base of the cartridge, I could have easily just connect the cartridge to a bench top power supply, and slowly pry off the goo. Under the state they’ve arrived, any attempt in disassembling/cleaning the hotsides have been extremely difficult.
So - if used, as-is, clearance, deeply discounted (95% off!) parts aren't what you're looking for, would recommend sticking to new parts instead.
