Interesting Electronics & Components - Any New Finds on Aliexpress lately?

[3dp]

With the Aliexpress Anniversary Sale happening this week, I’ve been browsing various stores there for inexpensive DIY electronics and useful tools that might be useful. Have you come across any cool new items or placed any interesting orders recently? I’m talking about things beyond the usual mainstream products like common Arduino boards or basic components.
Have you found any exciting new measuring equipment, electronic components, DIY electronic modules, tools, or useful sets and kits of electronic parts?

For example, I already ordered the things I attached pictures of:
-USB C (3.0) cable tester for about 8€ (I had a USB 2.0 one before, but checking all the extra data lines on USB 3.0 cables with normal breakout boards is a bit tedious)

-35MHz to 4.4GHz "spectrum analyzer" NWT4000 clone for about 35€

-Wireless endoscope camera NE3 for about 4.5€ (mainly because I found this Github https://github.com/haxko/NE3-Scope )

-Ultrasonic levitation kit for about 4€

Yes, I specifically came across these very cheap (fake) op-amps that don't work:

The TinySA is about $40, how does that compare to this USB version?
