I’ve purchased two sets from the seller SpeedCarbon11 on eBay and have had zero problems. One set is 38mm disc that has at least 30 cyclocross races on it and many miles of commuting. They set up tubeless just fine and have been completely bomb proof for my 140 lbs. They haven’t need trying, and the hubs still spin very well. At 1650 grams and about $420, I have zero complaints.
I later bought 50mm wheels from the same vendor, for about the same price, for use on my road and tri bikes, and have been just as satisfied.
That said I’m looking at Yoeleo for my next purchase, which are more expensive than my other sets, but evidently are quite aero and still far less than the big name brands.
