Its the only one that appeals to me because all the others have such terrible wastage. Whether it lives up to the hype remains to be seen but it has certainly shook up the other manufacturers.
As far as I know the completed hotend contains the heater and thermistor and is built in one piece so two screws and two cable connectors and it's out and easily swapped. I think the price of the hotends will be cheap too, currently they are $12 each on offer. also think Trianglelabs and other 3rd party vendors will soon have their own equivalents. With over 20,000 potential orders there is a definite market for 3rd parties.
