I bought the stereo microscope and am really excited! Heavy, solid build anything in the wobbles, clean fittings, precise drives and the optics of excellent sharpness and brilliance into the edge area (with 20x eyepieces allows the brilliance at 80x magnification after; the depth of field decreases logically at higher magnification anyway). Lighting with separately switchable up and / or transmitted light leaves no wish unfulfilled and the testing of insulation and protective conductor resistance and contact current revealed no deficiencies. Even at a higher price the instrument would be worth every euro! Conclusion: Very strong buy recommendation !!
