saw a few on here were interested.

they do look very nice, and reasonably priced too.

It is exciting to see some Chinese brands how they try to be as good as the Shimano, SRAM, Hope, etc.
These took good ideas from many models all in one.
Still 128g heavier than my Piccola's but Wow!

Saw these branded zrace too, look lovely tbh, might buy a pair just to see

[Lovewookie]

Just pressed buy on a set of the Zrace ones as they're about £20 cheaper than the Onirii branded.

will update when they arrive!

Keen to hear how they are.

Trying to figure out if they'll send them to me left rear right front before buying a set, do these use mineral or dot?

Just ask them, Aliexpress sellers are generally quite responsive

They use mineral. zrace branded versions can be bought as parts if you have the ability to recable. They also come in silver which looks pretty cool, shame they only come with the red circles on the caliper.

Really hope these calipers' fluid displacement/piston ratio is similar to Shimano and Magura so they can work with Shimano and Campagnolo levers.

Zrace said it's 425g.
I think they looked the same.

Not sure I would swap Campagnolo levers to another calliper.
They are too good to be changed 
Never fading nor rubbing.
The pads stick to the pistons that are magnetic.

They look like an updated version of the iiipro brakes.

IIRC the guys who had them in the german forums said that the old levers were for quite big hands, and I think one had the issue that a caliper was sweating a bit oil.

I ordered a pair. Will send pictures and feedback once they arrive.

[lilbigmacky]

These look baller af and for a good price. I might get a pair if people have good results with them. Do they use Shimano bleed cups?

[Fat Larry]

dunno about bleed cups and i doubt you'll get much sense from Onirii.. i've been trying to find out from what the equivalent pad they use would be but they can't or wont tell me beyond that they use their own E4 pads... anyone one recognise the shape?
