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

Marketed as a USB 2.0 hub with a single USB 3.0 port? When I last looked, typing truth via keyboards were free and valuable at the same time.

Why type truth when you can have some LLM generate lies?

I would expect at any price point the seller should not be lying about the specs.

Well then AliExpress is not the storefront for you

It's actually the importer's info from the Chinese manufacturer, not the OP, since it's the switch packaging (it'd be inside the original package they'd have received from Aliexpress)

AliExpress shipping is wild.. as far as I understand it they try to find the cheapest place to send packages from, so (living in Europe) I've received packages from Australia and Azerbaijan. They probably send a palette of stuff to a country that has cheap International postage, and from there the palette of goods get broken down and packaged for the 1000s of end-consumers..

I once noticed that there were eBay auctions with free shipping closing with no bids, minimum 1 cent bid. I wrote a script and bid on 1000 random items, all from China, all Aliexpress style items. Every single one of them was shipped from Mongolia.

One of the hopes I have for AI is that products like this become almost unsellable.

Gemini strongly disrecommends buying this product[1], but it's not clear if the opinion is based on Dr. Gough's review in-part.

This, of course, leads to another arms race where listings like this will be "AI optimized". They may have prompt injections, or simply specifically claim that issues like backfeeding are resolved when they are not.

And it also makes the AI companies an arbiter of what products are marketable.

Why on earth do you think an LLM would be capable of detecting problems with a listing like that without a human doing so first? LLMs are just as gameable as SEO, if not more so.

You can check my own project doing the same. It's a one key keyboard that also can be set to jiggle the mouse a bit. https://github.com/markomarkovic/nena-ilo-lili

Did you use generative AI to design this? Superpowers plugin? This is cool, but if you did use AI that’s another level of cool :) https://github.com/markomarkovic/nena-ilo-lili/blob/main/doc...

Agents are pretty good at this stuff, I coded a bike shifter button module with basically zero experience in the subject and it works pretty well: https://github.com/Klaster1/open-elin

The trend of slapping two STT 4-port hubs together is so common, that even name-brand hubs for reputable brands are often this, including the back feed issues. I purchased hubs form a solar-named company, and one that has a similar name to a large US department store, and they were cascaded 4port, STT, ganged overcurrent and switching. I've started buying PCBAs from Ali, where the vendor advertises the exact chip set…

Why not name the sellers?

I've yet to come across truly reliable Thunderbolt 3 and above stations. Seems like every brand has, like this 7 port wonder in the article, lots of 5 star reviews. When you dig deep into the weeds of the reviews, Reddit, user forums, etc., you find the undercurrent of people who actually bother to check the stats reported by their OS, or have disconnect issues, etc, etc. I'm somewhat sympathetic because from what I…

I use Dell Thunderbolt docks because that's what my employer gives us and as such I've collected a few of them. I've had zero issues with them. The only complaint is that the power button on the dock only seems to work with Dell laptops, not a huge issue since I don't think that's a typical feature anyway.

I've got a Dell USB4 dock on my desk right now. It has generally had pretty good compatibility. The only complaint I really have about it is that it gatekeeps higher PD options behind proprietary signaling so while it can technically output higher than 60W nothing but a Dell device will properly unlock it.

This isn't usually a problem for most of my devices. My Thinkpads just alert me and say they're not charging at full speed, ending up negotiating something like 58W or so. Similar things with other devices. However, I've got one machine that will not even attempt to charge unless it definitely gets 20V/3.25A, which this dock just will not negotiate to for non-Dell devices.
