I did … but via Aliexpress for around 90$…
But actually…I cannot recommend it.
The large lower pulley bearing is not very well sealed. Now you may say…it’s ceramic anyways…but this did not
prevent it to completely lock up! Because of debris entering.
So it’s a bit of a service intensive item. Maybe using it for my gravel setup is not the intended user case, but well.

Thanks, my ospw had arrived in the meanwhile. I've set it up, but have not put any serious mileage yet - just few commutes to office. But this Sunday I'll go for a ~130km ride. In the short rides it's been totally fine. My gears are not yet perfectly set up, but ... they do shift fineish (My comparison bike is latest dura-ace so wheeltop is obviously worse than that)

Maybe the biggest complaint I'd have so far is - it's not always ... clear whether you manage to 'click' the shifter properly. Sometimes it feels like I did press the shifter, but nothing happens (I'm not using the 'race' mode - maybe that helps as well)
