This is a fantastic microscope that you find yourself using far longer than you dream. We located and tested this unit and found the quality of the optics to be first rate, the lighting and mechanics to be excellent, and the ease of use to be perfect for our students. Magnification for 10x to 30x is what you will normally need. Darkfield/Brightfield, overhead and a rheostate make this microscope more than a student microscope. We take this scope to the Tucson events as our main microscope. Its that good for portable use. Comes with stone holder, eye guards, dust cover.
