I got the 50mm version recently, ran about 350km on it until now. So far they are doing just fine. They came true and stayed so after some running, actually including some light gravel use with 30mm tyres.
My only issue was, they came without preinstalled tape and the tape in the box wasn't enough for both wheels. That wasn't great, but no showstopper obviously.
Delivery to Germany was fast and smooth to my door. After ordering they asked me if I wanted DPD shipping toll included, it would be 37$ additional cost. I accepted and they send a link for another ali-payment from which I had to order a quantity of 38. Seems strange, but worked.
I asked them to send the wheels without any branding and stickers and they did. I like the matte black look. The spokes don't look as good as Sapim CX-Ray though, they seem rougher.
So all in all I'm satisfied and would recommend them at this price point. I'm coming from MTB, so I cannot really compare them to other road sets, how they feel, how fast they are.
