Review on Jiusion WiFi USB Digital Handheld Microscope: 40-1000x Wireless Magnification Endoscope with 8 LED Camera, Phone Suction, Stand, and Case - Compatible with iPhone, iPad, Mac, Windows, Android by Luckie Coonrod

I have several of these for some Raspberry Pi 3 B+ systems. The aim is to teach some children how to use the computer "in the field" the way it used to be. I had a few questions that the seller was happy to help with, but I will say that I would recommend Camorama for software if you use Linux based systems (Raspberry Pi in particular). I found this to work better than GuvCview. I suspect that the Raspberry Pi's RAM limit is causing problems when trying to use GvCview. Also, I've found that for my particular use case, it's better to plug the camera directly into a USB port on the Raspberry. The small WLAN module is decent and seems to work very well. So I'm going to use THIS part to install wireless cameras around the house. Thinking about it, since they are battery operated, I can connect them to a mobile system. Anyway, I digress. Unfortunately, the two buttons (zoom/snap) don't work for me on Linux. But it's normal; When was something easy for Linux? The system works as advertised, the seller is happy to help if you have any questions, problems or problems.
