I have ordered the microscope because I already own another of Bresser. Only the processing of this microscope I find personally not good, it looks pretty cheap. In addition, I have been looking forward to the USB function, and unfortunately had to find that this does not work with Windows 7, because there are no drivers for it. Have then want to test under WindowsXP, which was unfortunately did not go as the USB camera defective. Recently I sent it back.
