A microscope can have high magnification, but poor resolution. Racking the microscope from up to down optically projects an ever-smaller portion (field of view) of the specimen onto the microscopes CCD sensor. The result is magnification with increased resolution (limited by the optics and CCD resolution). The up/down buttons on the microscope digitally magnify by selecting a subset of the sensor’s pixels and digitally upscaling them. The image is bigger (magnified), but there is no increase in resolution (like watching SD programming upscaled on a HD set). The pixel density of the display determines the viewed specimen size on the screen. A good analogy is an HD video is much smaller on your phone than on a large-screen HD TV, but both have the same HD resolution. It’s just that the cellphone is smaller with a far greater pixel density. Magnification without increased resolution is sometimes called “empty magnification”. It is fine for soldering circuit boards, but not useful where both magnification and resolution are needed (i.e., cell structure).
I made the following measurements using a slide (w/ mm scale) and measuring the apparent size on the scope’s screen (no zoom):
- High point (Lowest Power): 22mm on slide measured ~90 mm on screen (~4x) with ~23x13 mm FOV
- Low point (Highest Power): 2 mm on slide measured ~90 mm on screen (~45x) with ~2 mm x 1.1 mm FOV
The digital zoom button (up arrow) provides an additional 2x zoom (~90x max on the microscope's display). Displaying the image to a 27” HD display provides ~6x increase in apparent image size, but no increase in resolution. I assume the CCD sensor is HD (1980x1080), but could not confirm.
Images were sharp with good color on the microscope screen. I would rate the build quality as average for the price. The lighting system is good (and adjustable), but could use better diffusers. The gooseneck lights are definitely needed at low focus (high rack). The UV filter is threaded, but attached with double-sided tape. The rack and pinon focuser had a bit of play, but acceptable in this price range. The barrel focuser was a little stiff. Wireless control did not work out of the box, but I was able to move the circuit board to make contact the battery (not included). No PC software was in the box, nor a download link provided; however, the seller did provide link on request. The instruction manual left a bit to be desired – but all-in-all, my initial impression is that it is acceptable for its intended purpose (i.e., viewing objects visible to the naked eye and circuit board soldering).

Got the microscope as a gift. It has arrived very well.

Brilliant! A great tool for everyone!

his Digital Wireless Microscope has a USB port and a WiFi adapter so that I can use it on a computer or a smartphone. That wide range of supported devices makes it versatile and suitable for use in fieldwork, where I may find myself far from a computer. This model also has good magnification, going from 50x to 1000x, in theory.
In practice, it requires special software to work. I am using Windows 10, and I was able to download the software (camera.zip) from their website mentioned in the manual. The software is portable and does not need any installation. The IOS app was good too, and I was able to take pictures and videos from zoomed samples. It also has excellent lighting. Bright light means you can make out more detail and get better images. The only thing I don’t like is that it requires repeated calibration with its measuring tool.
You should not expect a high professional microscope proficiency from this little device. It does the job, and I think it can be a nice gift for kids and older people who cannot see well.

Pros
Wireless
Good magnification
Wide range of compatible devices

Cons

Everything went great - thank you

The first device was defective but the second device is top I am very satisfied

The microscope can zoom in very, very far with very good image quality despite the wireless connection. The battery lasted more than 3 hours for me, and a stand is also included so you don't have to hold it constantly. The price-performance ratio is top

Very good
