Must Buy, highly entertaining
I had read mixed reviews on pocket microscopes but this one seemed to have mostly good ones and I am so glad I got 2 of them for my kids stockings! The images are so clear. I took pics with my phone without having the clip thing. Here are images of a blade of grass, moss, a dead leaf and a piece of fabric. Highly recommend!

Works Great -- re
An amazing, cheap little pocket microscope that works wonderfully. I suspect some of the negative reviews may be from folks unfamiliar with microscopes. Images are reversed in most microscopes -- confusing to eye and hand -- but just a matter of getting used to. Used in traditional fashion, with material placed under a glass slide on a table, this scope is unbelievable for the price. For folks wishing to use the microscope OTHER than on a flat surface, you can indeed focus hand-held, but you may need to be a little more realistic than some of the negative reviewers. At these high magnification levels, very small movement towards or away from your object greatly affect the focus, -- so, you'll want to start (or stick!) with the lowest magnification on this microscope for handheld use, and use a steady hand, or brace your hands against a steady surface if you can. But even with nothing to brace on, I had no issue in the field examining detail on objects I couldn't see with the naked eye -- just shakier than if braced! I have several jewelers loupes, and I like them and use them often, but the magnification levels don't match the scope for seeing detail on very small objects. It's definitely nice to have both if you routinely inspect very tiny items. Finally, the LED light is quite bright, and the focus and zoom knobs surprisingly solid. Amazing for it's diminutive size! And, seriously, detractors: it's a pretty awesome pocket tool, all for not much more than a cup of Starbucks and a muffin!

Limited use = limited appeal.
Good magnification. Optical distortion around the edges. Even the center image is soft. Definitely NOT optical quality. Very limited depth of focus and needs to be pressed against whatever you're looking at. Basically useless for non-flat subjects. If you're making smears on glass slides it's probably an okay choice. If you are inspecting odd-shaped things like flowers, it's flat out garbage. I'd never buy again.

Great nature study tool
This works surprisingly well. My daughter is using it to view everything—yarn, coins, leaves, printed pages, petals, fabric—she loves it. And it’s easy to use. Can’t wait to get outside with it once it’s above 0.

Disappointing and Frustrating in Equal Measure
I really hoped this would be a handy little tool, but unfortunately it fell well short of what was advertised. What went wrong: The first red flag was the LED light—not just dim, but not working at all. With no usable illumination, the whole purpose of the product was compromised. The build quality felt flimsy. The housing creaked and shifted when I tried to adjust or handle it, which made the experience feel unstable and cheap. It was difficult to use. The focusing mechanism didn’t move with any smoothness, and aligning the subject was awkward. When I did manage to get something in view, the image was blurry and lacked clarity. The magnification didn’t deliver the crisp detail I was expecting based on the listing. The product didn’t match the description. I was sold on the idea of a portable microscope with solid optics and illumination. What arrived felt like a compromise in every area. What could have been better: A working LED (or at least a warning if the sample unit has light issues). Fixed or solid internal components so the focusing and zoom feel reliable. Sharper optics so that the image clarity actually matches the advertised 60-120x magnification. Better instructions or support to help users get from “unboxed” to “clear view.” Final thoughts: This one was a let-down. If you’re looking for a dependable pocket microscope with working lighting and decent clarity, this product didn’t deliver. I really hope the manufacturer addresses these issues so future buyers don’t feel the same frustration.
