Worth the money
Good derailleur for the money, fits ok, little clunky on movement but it’s cheap so wasn’t expecting anything more.. no instructions for the setup so it was a little bit of guess work until you see it moving

Works well.
A decent entry level derailleur, make an excellent upgrade / replacement for an older MTB. I recently found an old full suspension MTB frame in decent condition, so figured I would build it back up into a bike to use if I could do it cheap enough. With some careful purchasing I only have around £70 in it, and the bike looks like it's almost new! Better than any complete bike I could buy for the same price... Derailleur works well, shifts smoothly and is easy to adjust. Looks good too.

Convinced these are factory seconds or returns
So bought one of these to replace mine that worked but was damaged in a ice crash, now it should have been a simply swap, it was delivered quick and on time however upon opening the box I noticed it was missing some key parts, so i did the return exchange and Amazon was like ok we will send out another but you do not need to return the original ( this turned out to be a good thing ), upon getting the replacement I inspected it and all the parts where there and i was happy right up to the point i noticed that the rivets holding it all together where not only missing washers but they had not been riveted properly, just by luck they did not want the original back so i was able to make one good out of 2 bad ones.
