"Didn't even last for a print , melted filament started to come out near the Copper Pipe and near the heater wire. Printing started and half way I smelled something burning and it was coming from the printer. When I opened the Printer Head I saw the melated filamemt on top of the hot end was the reason.Still going to order another one just in case i got a defective one"
