Review on 🔬 AmScope USB Digital Handheld Microscope: 50X to 500X with Adjustable Stand and 8-LED Light for Windows, Mac, and Android (OTG Adapter Included) by Chris Walker

This is the second USB microscope I have bought. I use them to fix and check electronics. The first works very well for what we use it for. This sometimes doesn't turn on when the program starts, or turns on and then freezes after a minute or two. But for $19 you can gamble and you might get one that works.
