Arrived pretty fast. Seems to be as good as the ones direct from Hosim. I use Banggood alot and ordered this differential to have as a back up for my 9125... Must take apart a grease properly.

bought 4 to have extra on hand. differentials look good and seam to move ok but a couple of screws were tightened a little too tight so one kind of bound up a little ( easy fix ) also one of the bearing packs on one side of one was bad and grinding but it will be an easy and cheep fix. but for the price I would definitely buy again if needed in future. also fast shipping thank you
