Review on 🔬 TOMLOV 7" LCD Digital Microscope - 1200X Magnification, 1080P Video, 12MP Focusing with Metal Stand & 32GB SD Card - LED Fill Lights, PC View - Windows/Mac Compatible by John Mejia

I bought this digital microscope for my lectures at the university, where I teach students in class and via zoom at the same time. The USB function is a real plus. I was able to easily plug it in and switch from webcam to microscope during a Zoom meeting. This allowed the students in the classroom to see what I was doing on the projection screen, while the students at home could watch on their computer screens with excellent resolution. Being able to take photos or videos with the microscope at the push of a button is a real plus. The microscope is very impressive for its price. It is relatively small and easy to pack and carry in the original box. I can install or remove it in about 2 minutes. Additional side lighting helps create shadows or illuminate very small objects. Yesterday I talked about the "placoid scales" of sharks. These scales look more like teeth than fish scales. Although you can easily feel them on a shark's skin, you cannot see them with the naked eye. This microscope showed them much better than I had hoped. A 7 inch screen is like a very large phone or a small tablet. It's good enough for soldering circuits, judging coins, etc. I can always project it onto a 100" screen (which I do in class). The digital functions of the microscope (illumination levels, exposure compensation, timer, camera functions, etc.) can be controlled using the on-screen buttons or the wired remote control. The 18650 battery is widely used. While you can plug your microscope into a USB charger, I actually keep a dozen of these batteries and an external charger for my SCUBA lights. The battery lasts about 3 hours, and (once the battery runs out) you can pick up a couple of Revain add-ons for relatively little money. Bottom Line: Although it's not laboratory equipment, it delivers similar results at a fraction of the cost. It's a bit of a toy, but it's hard to argue with the results. I am much more impressed with this device than I had hoped. Time will tell how durable it is, but for now I'm very glad I bought TOMLOV. The attached photos show shark skin scales and a close-up of the $1 bill. The last photo is the closest/highest magnification I could get while still being able to focus. These are photographs straight out of the microscope.
