We bought the microscope for school and leisure / hobby. For this price, absolutely great. Many convenient features and well made. From the same manufacturer, there are also microscopes for beriuflichen everyday. Therefore, probably the good workmanship. Reflections on the PC are not quite as good as direct viewing. What would make the microscope even better would be a light from above. I know from my professional life. Therefore only 4 stars. But as I said, great for the price.
