This is pretty dumb. How hard is it to assign a serial # to each groupset? Their warranty process is just pure laziness. The EDS TX is already in Shimano 105 Di2 AliEx pricing territory. At least with the 105 Di2, spare parts are plentiful and quality assurance to chance buying from a reseller is much better.
It has serials - I don't think it's a problem of identifying their own product but rather they've come the decision that the purchasing retailer/channel is who would handle warranty issues. For my issue with the adjustment screw, the AliExpress seller was happy to deal with it, I just had to get it back to them in China. I ended up just fixing myself.
Definately will limit acceptance outside of Asia until they can improve servicing globally. Unfortunate. It will be a small niche of people like the ones in here willing to accept the servicing hassles that will be buying.
