It offered the net several cheap microscopes which are all made of this tube with LEDs. This one has a satisfactory sharpness. However 5 megapixels are unnecessarily much and can not be exploited. So 2-3 megapixel range completely. The stand and the focusing rack but are a disaster! The wobbles like rubber, so that is not possible a focusing! I made my own stand from a solid wooden board as well as a 16mm aluminum pipe from the hardware store. The Focusing I have expanded with a precisely machined 2.5mm aluminum plate that fits into the outer grooves. So you go. Tip of the manufacturer: Provides the satisfactory appearance with a good adjustment mechanism for the double! I would also pay 200 Euro for a better microscope, but there's nothing on the market.
