lol yeah it's pretty tricky I guess, more or less user error but I had one that didn't print and have 8 or so still working. There wasn't one that had a drip system combined so this came out of what was already around at the time, they work very well but the nipple where the line or 1/4" quick connect fittings goes, broke off after a lot of stress out on, it definitely needs redesigned and needs more layers on top surface.
