The good:
1.  I got it from LTWOO's official account on Aliexpress and they are pretty good at helping.  They did ask for a video to confirm and sent it to a tech.  By the next day, they had already agreed to send me a new unit.
2.  Based on the photo they sent me, it looks like they are sending the most up-to-date rear derailleur.  Hopefully, there isn't any issues with compatibility. 

The inconvenient:
1.  I had to pay for shipping, which I was prepared to do.... But I wasn't expecting it to be $65.  I was thinking around $20.
2.  Time difference is a factor in how long the process takes.  Obviously, they are in a different time zone, so it took about 5 days of talking to get it all sorted.

The new one doesn't have a charging port at the rd. They moved it to the fd. Seems like you'll be unable to charge?

Those look great, but I can’t find any info on them on the farsports or wheels far website. Do you know how I can find out more/order?

I contacted them through Whatsapp and they gave me a big list with this included.

Flashing the red light means it thinks it's at the end of its travel when it's working. Could it be that the end stop is being depressed because some stuff slipped?

There's no way to switch which button is up and which is down on a given side, right? When sprinting I'm struggling to hit the rear button on the right to get a harder gear.

I'm working on getting the fd tuned properly. When I'm using the adjustment button it seems to move in and out instead of just one direction. Does anyone have any tips? Should I be in the first click of going up to the big ring, or the second click trim position?

I ordered the ones from ec90 and they sent me their track bars on accident. They've been pretty slow to respond unfortunately. The track bars are quite stiff so I'm not too worried about the road version assuming it's the same mold without horns. Hopefully they send me out the new ones soon

I imagine non integrated stem will be a better user experience because people might not realize how long they need to go.

I have the non-bikedoc ones coming right now. We'll see how they are. I personally would want the same hoods, but more flare. More drag, but at least sprinting might be a bit easier. I do wonder if more flare would lean the levers in too far though.
