They show up quite a lot in accessories on AliExpress, like USB cables, hubs, chargers. Small electronics stuff. One of those semi-branded things out of China, the kind that feels like they're trying to build a brand rather than shipping crap as quickly as possible. The USB hub was fine. Something like a NAS feels like a sensible next step if they want to grow margins.

I bought a phone holder, USB hub and USB to SATA adapter from them. It works as advertised, but personally I wouldn't recommend buying anything too expensive from them.
