Bought it as an upgrade to my bike. Fitting was easy and tuning took some effort but for an amateur it was expected.
Working great even after 2000 km
Shimano Altus M2000 9 Speed Rear Derailleur (Black)
Very nice, no compromise, real shimano product only the cod is little higher..
Packing was good, delivery on time and the derelliure is working great. I'm using it on 3x8 drivetrain and to be honest it's smooth as butter but, only thing is it took me half an hour time to adjust the limiting screws and the barrel adjuster
It's better than acera and no difference between alvio just the wait difference of 2 grams
