Review on 🔬 Gray USB Digital Microscope Camera 40X-1000X Handheld Mini Microscope for Students, Engineers, and Biology Lovers. Compatible with Windows 7, 8, 10, Android. Ideal for Microbiological Observations by John Ghattamaraju

Good, clear, high resolution image with proper focus. The mound is cheap, making it difficult to focus and zoom. I use it to check the edge of sharpened knives and it works well for that. I'll probably build a jig to keep it in fixed focus and fixed zoom, which will do for me. Just note that if you're buying the camera for something else, the included mount is made of lightweight plastic.
