OEM quality
This was an exact manufacturer and model replacement of the derailleur that was originally installed on my mountain bike so the quality and performance is exactly the way it was originally. I was able to make the minor adjustments to match my gear shift ratios without any issues.

It works
This has to be the most cheaply made Shimano derailleur I’ve ever seen. Yes it does work, yes it’s easy to adjust. That’s about it. It is flimsy and Noisy! Great for a cheap bike your trying to get rid of
