So is the frame quality actually as good as Hambini says?
I'm also curious about the weight of the overall bikes that people on this forum were able to reach.

I built up an Onirii One about a year ago (regular ONE not the ONE Pro). I thought it was actually pretty good. Once it was built I definitely had some fun riding it. I had a lot of questions and their customer support was very helpful with answering them all. That being said, later we ran into an issue over them mislabeling their barstems and sending the wrong size and it got a bit annoying from there. That whole debacle was pretty frustrating at the time but I did end of with a (free) second barstem so it wasn't the worst (paypal refunded me because onirii refused to admit their mistake). I would hope. a year later, they have that sorted out. Their bikes do tend to have tiny headtubes so look out for that. My beef with their aero bike is that you probably either have to ride with pretty extreme saddle-to-bar drop or you have to add a bunch of headset spacers, negating the cool, aero cockpit situation.

With the bar pointing upwards like the top tube the drop might be a bit less extreme than would expect but yeah, it looks like one of those Chinese frames with an absurdly low stack...

99% sure that Pro is just a R088 with different paint and 150% markup

Yeah, their claimed weight is a bit higher that Spcycle for a bare frame (without their paint job), but otherwise they look identical.
The Flash looks like a fully integrated version of the 2018/2019 Look 795 Blade RS with a China-style lower stack (15mm) and an overall slightly different geometry, but IMO clearly inspired by that bike and their aerobike is clearly inspired by the S5.

I wouldn't buy a frameset, but their costum painted fully built bikes that they are selling via Aliexpress seem decent value for money, the Ultegra version bundle also includes their lightweight look-style pedals, a helmet + an aero bottle.

If someone wants to order a fully built Chinese bike they are probably not the worst option.
Their aero bike looks pretty sharp and fast to me (well, it's an S5 clone...)

Looks like a really bad mash-up between the new Colnago and the Madone rear hole.
I kinda liked the previous Falath Evo, had they just reduced the distance between the wheels and the frame a bit more and gotten the weight down a bit it would have been a fine aero bike. Then again, Elves sales are imo mostly carried by their fancy paintjobs.
