i would definitely buy this kind of frame from a more trusted source
This is an illegal product. It's not half illegal or in the grey area. It's full on illegal. So the concept of "trusted source" in this context is like giving your kids to your heroin dealer while running an errand.
Well seems extremely heavy so I would not buy a copy
Beyond the weight itself (currently reads 1050g±50g (size xs painted), which means 1100 in XS), the danger is a product that rides like a dog because they don't want the publicity of frames imploding (like the recent SL8 fakes with the exploding forks), and because it's a frankenstein design, instead of spending the time / employing qualified people to come up with a good layup, they're just putting a $hit ton of carbon everywhere. Some will remember how bad the first aero bikes felt, or how bad the first disc frames felt.
For this design especially, i think you can expect a genuine gap between how the real and the fake ones ride. When you're looking at an SL8 with mostly round tubes, i think you're a lot safer.
Nothing will stop a cringe baby from buying one of these (which is also why these chinese sellers simply do not need to do better), but for people who actually want to ride the bike, and enjoy it, if buying a fake, i'd stay clear of extravagant designs.
