I have this exact set and use them daily. Keep them plugged into random ports on my portable USB C hub / dock, so they don't get lost. That why I can use it for about anything imaginable from docking / charging my laptop or Steam Deck or just when I need extra ports or an SD card on my desktop.

Hack I learned recently:
If you have a device with a USBC port that supports charging but does not support power delivery (usually some cheap doodad) and all you have is a USBC port with power delivery, attach one of these to a USBA to C cable to make it C on both sides and it'll charge at the standard 5v.

Nice idea; I have some devices like that, like my massage gun.

One direction is USB 2.0 speed and the other is 3.0 speed.
B0D841YG3M $3.88 for 4 is one with 3.0 speed but only one direction (USB A male to USB C female).

Found this from the same company you posted that does both directions like the original post. The negative reviews about quality make me a bit leery though. Decided to order both and make a decision when they arrive tomorrow.https://a.co/d/2S1uIR2

You described the exact reason the USB specification doesn't support extension cables.

Good question. The Basesailor one is higher quality for sure, felt more weighty in the hand. But ultimately keeping the one I linked since I thought the faster speed would be worth it and these are just backup adapters to keep in my cable drawer. They're more likely to fail at some point due to worse construction but I decided I was okay with that at less than a dollar each... Will just buy a higher quality one if a specific need arises.
