I'm very happy with this device. I use it to monitor my cannabis trichomes (see pics). Just a couple of things to be aware of. At such high magnification the slightest movement of the device makes it extremely difficult to find and focus on your subject (it's virtually impossible to use it in your hand). Unfortunately the zoom, focus and lighting controls are located on the device, and every time you touch it the view swings all over the place. It has no built-in attachment capability for a tripod or any other stabilizer. My fix: I mounted the device on a solid immovable object (piece of wood locked in a heavy vise), I position the lens using the vise at the correct height for my subject, move the subject around under the lens, and gently adjust the controls. The other issue: changing image resolution in the settings menu appears to have zero effect on the live image or the photos you take. But maybe that's because of my camera or operating system or something else on my phone. It might work on your phone. Otherwise I'm impressed that such an inexpensive device has incredible magnification and image/video capture capability. More than adequate for my current purpose. Highly recommended.
