I've had good experiences with Jackly bit drivers. I have a portable electronics screwdriver I keep in my preparedness bag at work, and some more sets at home. They don't harden the bits but for what I use them for that's no problem. I also have pic related as my non-electronics screwdriver in my work preparedness kit, albeit with a different set of bits. I paid like $3 or so for it and it works great. Magic word for this one is "L-shaped screwdriver" if you're interested. They take standard bits with a solid lockup. Nice for light-duty sorts of things like assembling a chair etc., just choose your bit selection wisely.
Before they got overpriced I really loved James Donkey mice. I still have a JD keyboard with Gateron blacks as a backup.
Ganzo makes good knives. I have one of their models that's a knockoff of a Paramilitary 1 with an axis lock, I paid like 15 bucks for it and it has very good build quality with okay steel (440C).
When fidget cubes were the fad I bought several knockoffs for a couple bucks each and every single one had a single thing wrong with it, which was different for each cube. Hilarious.
I exclusively buy my phone cases off Aliexpress, I spend like $3 apiece and they're all great.
I got a 2kg scale that runs off AAA batteries for weighing various EDC items and Aliexpress purchases and it works great. Also got cheap digital calipers that do the job nicely, various little pouches and cases (Maxped knockoff pouch for $7, just as good as the real deal), spudgers, Mixza micro SD cards (I think they might be overpriced now though), one time I bought a Famiclone and I was able to get it for free because cartridges were a REALLY tight fit, so I sent them a video of me pulling really hard to remove a cartridge and I got a full refund, still works great though. I've also bought stuff like lighted loupes (highly recommended, they're dirt cheap and work great, just make sure to get the ones that take AAA batteries) and various charging cables.
I don't buy as much chinky stuff as I did 5-8 years ago but it was very fun.
