Beautiful Set of Bresser microscope with decent performance. The microscope has been paid to our son for a birthday, but is not yet suitable for primary school students. A later use of the microscope for school and hobby applications is very possible. The processing and the quality is fine (with us is shaking the lens head a little). Some points to improvements in design, there are also, as a stronger LED light and the electrical connection at another location would be (not the back) makes sense. Otherwise, everything is fine and the microscope can be recommended.
