Key attributes include a retail price around $840 with shipping, frame weights ranging from 685g to 845g depending on size and layup, and a 30mm listed tire clearance (though users report 32mm tires can fit).

Received my Onirii One XL (56 cm equivalent) frame. It weighed 685 grams minus front derailleur hanger and bolts for water bottles. Fork was 382 grams. I would post scale pictures however I guess since I am very new to posting I don't have that option yet. Interior finish seems well done. I'll be waiting ( rather impatiently) for my Avian Canary 400X130 integrated handlebars to be made in delivered for the build out. Hopefully pictures to follow
