The big ten-inch screen is the hero and what sets this digital microscope apart from others with smaller screens. You can see more and do more with this larger screen, from precise circuit work to classroom biology, this microscope has it all. Multiple lenses, a large metal base, separately adjustable base lighting, a slide viewer with its own backlighting, and integrated LEDs surrounding the camera… all contribute to setting up a great picture. Lots of options too, such as the ability to store images on the included micro-SD card, a remote, and HDMI output to a TV when presenting to a large group. The clarity and resolution are amazing, but the weakest link is the aluminum stand, which screws into the base and provides the track to hold and vertically adjust the microscope. There is no resistance; it moves up and down the track freely, with and without the assistance of the side knobs… and if you release the set screw too much, the microscope and display assembly can come crashing down onto the base. I will have to come up with a solution, either a tight rubber O-ring or clamp to limit how far down the scope can go without hitting anything… either way something to be aware of if you decide to purchase this… itʻs still an amazingly useful piece of equipment though.
