What's the story with this cable?

SmallRig USB4, 40Gbps, 240 W

Amazon in 2025

seems to work as advertised

Anything else

amazon product page - https://a.co/d/0iukNUjA

whatcable prompted "report this cable" - just supporting devs

also, I didn't see SmallRig branding in potential dupes so that seemed worth mentioning since that brand sells a lot of stuff to price sensitive folks on amazon

thanks!
