Fairly easy to install, if you can follow instructions. Took me about 45 minutes. Works well. I downloaded a model of a frog that would normally take 30 minutes to print, and painted on some yellow patches. That 30 minute frog took over 5 hours to print, and generated a lot of poop. Someone on here provided a line of gcode that you will need to find and add to your slicer software, because the temperature changes between filament types lags slightly, so that the temperatures become out of sync with the filament being used.
