Good in an Emergency
My NX derailleur got bashed pretty good and wasn't working well at all - I needed a replacement right away as I have an MTB trip planned. I put this on because it was the only one that Amazon could get here in time besides the XX1. It is not bad at all. I can't speak for durability, but the shifts are just as precise as the NX.The only real difference that you should know about is that the cable housing and cable routing are slightly different than the other Eagle groupset derailleurs and it requires a bit more housing length to make a proper loop. So you'll need a couple of inches of slack in your housing (at least) and some extra length on your cable as well. Other than that - no issues!

Not bad for the price back on the trails

So far so good, nice replacement
This derailleur is pretty much identical to the one that came in my eagle setup except, it has a wheel for the cable to rotate on which so far, seems to have given me smoother shifting. Great part at a great price!

So far so good
It’s a derailleur, it moves the chain. 👍🏼

The mysterious shapeshifting derailleur!
From day 1, the bolt connecting the derailleur to my hanger shook loose, and would need to be tightened multiple times per ride. This was annoying, but I was willing to tolerate it because it’s cheap.Then, 6 weeks after purchase, the derailleur bends for no apparent reason in the middle of a green trail, and warps my chain along with it. No crash no nothing. Both parts now unusable.Save yourself money and gray hair and get a crappy fake groupset from a brand you’ve never heard of. It’s likely higher quality 🤣

Does the job
I purchased this SX derailleur because GX & NX were out of stock and I needed a replacement asap for a trip to the Kingdom. The SX surprisingly did the job. Although it's a little slow to shift I was able to adjust to it. Didn't let me down & still using it 3 months later. Good product

not worth it - go shimano if you can
happy nice shifting first ride. fell apart on second ride. I did not crash. The derailleur did not hit the spokes. Long walk home. My Sram nx only lasted a year. Very disappointed in Sram, I expect better from them. I inspected the SX I found the cage bushing already had play in them ... poorly made.
