While definitely not being a real jhead, no where does it say that it's a E3D hotend. It's a hot end, and it's similar, but it doesn't claim to be what it's not so I don't think you can call it a counterfeit. Maybe a knock off...and a cheap one at that. Caveat emptor...you get what you pay for...etc...Quote

With a real E3D hotend you should be able to screw the nozzle into the heater block so that there is a slight gap between the nozzle and the bottom of the block, then screw in the heat break until it makes contact with the nozzle. Then screw the heat sink onto the break. If it spins all the way down without tightening, then it was either threaded too far or the break is two short. But there definitely should be a break there. Having the heater block contact the heat sink defeats the whole purpose of having the narrow break.

It's a poor artist that blames his paint brush.

That saying does not really apply here unless you mean it in the sense that a artist buys a brush without any bristles and paints a horrible picture then tries to blame it on the brush.

Teflon lining and an advertised limit of 300C?

With no PEEK or PTFE in hot regions of our HotEnd we can reach 300C with the supplied thermistor. By swapping a thermistor for a thermocouple (may require additional electronics) you can reach over 400C.
