A very solid processed microscope (acts like made in Germany), which makes its genre proud. It is nice and compact and so does not take away so much space. The software worked after the first start-up (under XP installlieren only the program, not the driver, because this will cause Unstimmingkeiten). Actually I would be fully satisfied and would 5 Puinkte forgiven, but trigger gives it unfortunately weil.der cross table was stuck and had to be replaced (also available at Amazon, you only have to replace the thumbscrews) and 2. The largest lens so bad and dark features that you can not use it in practice - one sees only fog and dust particles. I have to balance halbwertigen acquired two eyepieces of 20x and 25x, which enhances the magnification. They are better than the attached, but only fit directly over the microscope, not in the Barlow lens use, so that I, when I use them, have to do without the Barlow lens and yet possess any full magnification. So that's 2 points deduction. if you had a better lens for the greatest use, I would have given full credit, since the microscope is really beautifully designed and crafted. The camera works wonderfully when they return is also on enlargement behind the "normal" use.
