This is a really neat tool to have! The camera is so good, I didn't expect it to be so clear. I know it says its for ears, but theres a lot of other uses for it. I originally got it to investigate one of my ears, I have been having hearing problems with it for a few years now. I can take pictures deep inside my ear to show my doctors next time. It was easy to set up, my phone (LG g5) uses a usb c type connection, and so it requires a usb c to micro usb converter, but other than that, just download the app, plug it in and your're done!
