Well, of course there is the "buy cheap, get trash, duh!" talking point. But if I pay more, who's to say I'll get a better product? The OEM or some middleman or whoever might just pocket the difference and push crap anyway. Well-known brands have done this as well, either intentionally or because they got shafted by their supplier as well.

I have one (ANKER IIRC?) that looks very much like this, but with two-position buttons that actually cut power, and USB3.0 level connection on all ports I tried. Also comes with the proper power supply for the barrel power connector. I suppose this one is a knock-off of mine :D

This has been a problem for a while. It's Akerloff "market for lemons" applied to technology. Sometimes however you gamble and win, discovering that the Chinese device actually is really good for the price. Occasionally even better, when you discover that some anti-feature like DRM is either not implemented or trivially turned off.

This is my favorite version of this dynamic, intentionally buying the crap because they cheaped out on the antifeatures.

I think that I have the same exact USB hub. I personally don't care about the USB 3.0 issue mentioned because it's only used to charge some devices. I think it's a controller charging station, a radio charging station, wireless charging station and a small device for rechargable batteries

My first thought whenever I come across such a badly-engineered no-name device is "oh great, another bad reference design which will poison the pool of all the available devices out there" It helps a bit to spot and avoid that exact exterior design, but often those devices are designed to reuse the same mold as more-expensive ones and/or keep changing the design based on the purchasing customer. So you end up on AliE…

"Ah, that's Rev. B, yeah, known problem..." Like I could somehow buy by PCB rev. Sometimes they even swap entire controllers within the same Rev.

$5 USD. What did you expect? Always surprises me when people pay essentially nothing for a product and then complain about quality.

Right? This is basically one small step away from stuff like “2TB usb stick for $20” scam listings on AliExpress. Of course it will be fake or crap. Cool tear down and write up though.

It used to be that cheap android junk devices would just give you a root shell with "adb shell" - no need for root exploits or reflashing - while expensive devices would give you a locked down shell.

I've definitely realized this in a couple of markets: Buy cheap, get trash. Buy expensive, get expensive trash with better marketing. Working with power tools from various brands has made me realize they all cheap out in the same ways. Plastic gears where there used to be metal, undersized motor drivers that fry themselves under sustained load, trigger switches that start misbehaving or die completely after a few mon…

This wasn't the case 20 years ago. There was actually a good article on HN a few months ago showing how most of the brands are owned by one company that has ruined them all. Still a few good brands. Need to research https://news.ycombinator.com/item?id=48147665
