Overall I find this borescope very good once in use. However, instructions for use with listed as compatible Linux OS are non-existant. With Android, I recommend you use the USB Camera app that is pictured in the instruction manual for ease of use. Unless you are extremely tech-savvy. I tried the other endoscope Camera apps, but could not figure out how to get them to work. The picture quality is excellent, and the adjustable brightness of the light is a great feature. This is a very useful tool, which I'm sure I will find additional uses for.
