This is an fine little microscope, solidly built, portable (with a light-weight, well-designed case), easy to set up, and simple to use. The manual is clearly written and useful (except for at least one minor error: the camera icon is not on the lower left but upper left of the LCD screen ["Taking Images" p. 7]). The camera functions well. The high resolution still images I took (of blood and blue cheese) are fairly clear, and the videos of a tiny drop of aquarium water show an astounding assortment of active (albeit soon to die) microorganisms, probably in better focus than the ones observed by Leeuwenhoek. I now know why my fish seem to do well even if I forget to feed them. Illumination is appropriate, though clearly best suited for viewing transparent or semi-transparent specimens. I was especially surprised by the large amount of internal memory which, coupled with the video file format (3GP, normally used in mobile phones) permits a stunning number of image and video files to be stored. Downloading to a computer using a USB cable (supplied) is very easy - the camera simply shows up as a removable disk. If necessary, shareware conversion programs for 3GP to AVI or MPG format can be found and downloaded in a matter of minutes. The date default setting to January 9, 2031 is, however, more than a bit futuristic and might be a bug. The microscope I ordered did not suffer from the black spot on the monitor mentioned by several reviewers. I recommend this microscope to best.
