Haideli - Tideace - SP Cycle, all the same, afaik, Across aliexpress and the internet, you can find a few more pics. I think there's a review of it on YT as well (in english).
I considered this frame, then went with something more aero looking (pure vanity). I didn't find anyone saying bad things about these brands / frames. If you buy one, please report on your experience here!
