I was not expecting much at the price. But me the microscope has very surprised. The processing has a neat appearance. The lighting can be adjusted via a controller. First I tried it on my tablet over an OTG USB cable. I have used the app CameraFi. I connected it and immediately it was detected. Everything without problems. Then I tried it on the PC (Windows 7 64bit). The CD was not necessary. Windows has the necessary drivers themselves loaded. On the PC I have tried the USB Microscope with VLC, ToupView and the program Measurement of the CD. Again everything worked without problems! The quality of the recording is good and more than adequate for me.
