bought a portable microscope for $10.00 over 40 years ago. I found it very useful when I was in the truck tire business. I can place it on the tread of a truck tire and determine the direction of the wear pattern to solve alignment or other tire wear issues. For me, a typical homeowner, the microscope solves the timeless and all-important question: termite or ant! Of course, the images from my antique microscope are limited. Focusing on the insect in question took a great deal of time and patience, and at least a dozen of these villains were captured with duct tape. Still, your efforts will be rewarded when you know you don't need to call the exterminator. Pink frame Wi-Fi digital microscope is much easier to use. In comparison, the features are rechargeable so no batteries required, the subject is easier to locate, the image is visible without squinting, you can photograph the subject, it's easy to focus, and the image can be of more than one person at a time to be viewed as. Setting up this unit was a breeze! No major assembly effort, just charge the scope, place it in the stand and download and install the application. Note that the device broadcasts its own WiFi and does not connect to yours. While using the microscope, switch the connection from your home WiFi to the one in the microscope, observe the object, take pictures, and switch WiFi back when you're done. Insect subjects don't stand a chance!
