Only been using it short term but so far working well with abs and pla. yet to try tpu. increased e steps from original at around 100 to over 400. the tensioner spring supplied was way too stiff and i was concerned it would cause issues squashing filament (been there before with metal mk8 extruder upgrade squashing the filament so bad that it wouldn't fit through the heat break), so i swapped to something more suitable i had laying around. supplied bolts were also a touch on the short side for the thickness of plate it was mounted on, only giving about 1.5 turns of thread when tight so i replaced them with some that had to be trimmed to exact length. it is set up as direct drive on ender 3v2 with 2 piece plate that lines things up very well. time will tell on longevity, but so far happy with purchase
