Real stereoscopic or USB microscope? Or both?

My new microscope: http://bit.ly/2ONJB38 Stereoscopic microscope: https://goo.gl/L5AS18 ELP cameras: http://www.webcamerausb.com/ Patreon: https://www.patreon.com/marcoreps While a common USB microscope is ok for inspection, I wouldn't want to work with it. Short focal length, low frame rate, shaky stand. This affordable stereoscopic microscope does everything a lot better and additionally allows real 3D perception because of its 2 separate optical paths.
