So there would be a "mark" left of failure, I've screenshotted the review - otherwise once the seller makes a new listing, the proof will be lost to time. (I blurred out the actual person though out of respect to him as the injuries do not look nice - skin torn off from cheek and nose)
looks like the mounting interface on the stem is carbon. That's insane, should be metal, there's enormous shear force there when you're using the extensions and hit a pothole for example, which is why alu round bars with clip on bars always worked because the stuff would just rotate on impact (just like your bars turn around the steerer when you crash). The energy has to go somewhere.
And so, it looks like yet another beta product that's just released into the wild expecting people to beta test it.
For reference, most of the chinese frames we're buying are exactly that, btw. The frames we get excited about on this forum do not go through iterations with riders testing them. We're the testers.
The hubs for carbon spokes with no retention for the spokes is probably one of the stupidest examples. Although, to be fair to the infinite stupidity of American engineers from SRAM / Zipp & Enve, hookless for road wheels is just a level of stupidity that's hard to comprehend.
