Anyway, I have the same ones, ordered from Aliexpress, on my gravel bike, and wife on her road bike.

Of course I'm far less miffled when a random aliexpress purchase turns out to be a bit crap then if I paid Trek branded pricing for my cheap chinese stuff. On my road bike I've got a set of Decathlon CF cages which are fully reliable, and were something like 18 Eur or such, which I found to be fair - they're consistently the manufacturer which offers the most "value for money".

One broke after my kid climbed on it while the bike was sitting in the trainer, which I don't think the Bontrager branded one would've endured, either.
