Review on High-Definition 2MP USB Microscope: 40X to 1000X Magnification - Digital Camera for Inspection, Endoscope with Carrying Case - Compatible with Windows 7, 8, 10, Mac, Linux - OTG Android Phone Compatible by Brooke Nelson

This is a great little digital microscope, well built and the zoom control isn't sloppy. Problems arose with minor repairs, for example, when changing the battery in a watch, as you can see, this is not a problem now. The close-up sharpness of the coral is excellent. Buttons to control light and photos work perfectly. Also records videos. Easy enough to use and my young grandkids enjoy exploring too.
