Did it despite the signs that the software does not work on Win7 bought and simply another WebCam loaded freeware program from the net to make it work properly. About a missing part I became quickly agreed with Amazon and it was resolved to my satisfaction. Since we microscopy at the vocational school at present I have the comparison to more expensive microscopes and must say that it's bad in comparison, but I also at home may well look at the preparations for example starches. Color filter I'll probably just still tinkering of tracing paper, otherwise I'm satisfied.
I would recommend it where parents take children for some time or that are so old everything myself to understand and possibly at some questions read in books or on the net, it's just not a pure toy but even more of a "working tool".
