I bought one. It looks really good. Makes an OK desktop microscope. Works with Linux on the desktop. I had to download the app to get it working on my Samsung S4. The mirror is not great. I haven’t cleaned particularly well, but the glass seems cloudy. Best without the mirror.

Thanks! Will be 2 meters enough?
