The microscope serves its purpose, it is handy and lightweight. The quality of the optics is significantly better than expected for this price. The only drawback: the graduated scale is out of focus and can not focus, unfortunately, a diopter compensation is missing. (For this, I would spend even a few euros more)
The illumination is sufficiently bright and illuminates the objects to the side, be in "regulatory preparations" (ie, not transmitted light, not transparent), the surface structures well modeled by light and shadow, and are so beautifully evident.
