More expensive than cheaper. I have tried about 7 of these small pocket "microscopes" for insect identification in the field and at home. Many are less expensive; some are much smaller. But for now this is the best because 1) the magnification is more than enough for my purpose and the resolution is excellent - I can see the hairs on the ants' legs clearly and sharply. The optics are good enough. 2) it runs on a standard AA battery instead of the tiny/expensive watch batteries that most other scopes require, 3) it has a secure grip so you can hold it very steady with one hand while focusing with the other , and 4) it's very comfortable, with a quick coarse focus lever and a separate fine focus knob. 5) The LED light is offset so that the beam hits the sample at a 40 degree angle. This is important as it eliminates reflective highlights that can darken the image. 6) Optics - good enough Someone really thought through this question. The only downsides are that 1) the Carson is quite bulky compared to many cheaper ones. You can still slip it in your pocket, but it's about the size of a pack of cigarettes (in the field, I slipped a tiny $4 x 60 scope/magnifying glass into my fanny pack). 2) There is such an easy way to take a picture. To do this, I use a small $10 60x scope/magnifying glass that attaches to my smartphone. The high resolution (10 megapixels) of the phone's camera allows you to zoom in on details. 3) The light is not dimmable and sometimes too bright.
