It should be noted that despite the ridiculous price, this microscope really increases and is quite suitable for examining the cutting edges of tools, SMD components, or similar small parts. The considered surface is highlighted by three LEDs. We also point out that the backlight is controlled by a three-position toggle switch. So, device equipped with two backlight modes - bright white light and ultraviolet. The kit comes with a microscope case made of artificial leather and instructions in English. The stated magnification of such a microscope is 60x. The dimensions of the device are 38 mm x 35 mm x 16 mm (L x W x H). Its weight with batteries is only 18 grams. The backlight is powered by three batteries of the LR1130 type (not included!) The design of the microscope is movable. The minimum focusing distance is about 3 mm.

Of course, the functionality of the device is not comparable with its "older brothers", but its price is much lower. Advantageously, it is distinguished by an extremely compact design, so this device can always be carried with you and, if necessary, used in “field” conditions, which cannot be said about full-fledged usb and ordinary microscopes. Note that with the help of such a microscope, you can take decent photos of all sorts of little things with a smartphone camera.
