It's certainly not a professional-quality microscope, but it's not intended to be. It's a toy and a pretty good one. It's small, light, and will fit a child's hand well, and is simple to use. It comes with a mini SD card installed, a USB C cord for charging and connecting to a computer, and several microscopic slides containing such things as dandelion fuzz and goldfish scales.

It has built-in LED lights to light up whatever you're looking at and the brightness level is adjustable. Magnification is 100X to 1000X and there is a conveniently located focus wheel. It even functions as a camera and a telescope, which is fun.

The viewing screen flips out from the side. The screen is tiny, but, with a little fiddling with the focus wheel, the image is relatively clear. Images can be saved as either photos or videos or watched live on the screen or on a computer screen when attached via the USB cord.

The unit is plastic, and although it seems sturdy enough I doubt if it would survive a drop onto a hard surface. There is a hand strap on the side to help prevent drops and steady the unit.

Overall, it's a good child's toy with some cool features and most kids interested in studying the natural world should be fascinated with it.

This little infrared viewer works great. It is on par with a smart phone camera, with the added benefit of infrared for low-light/no light situations. It has a camera resolution of 12mp and video of 1080p. The manual focusing lens is very easy to adjust and helps produce sharp images. Its 8x zoom function is not especially powerful, but thanks to its sharper focus I can live with that; these aren't binoculars or professional grade cameras after all. The viewer screen color change to green or purple is a quaint feature but not one I'm likely to use any time soon. This viewer is substantially smaller than my older one, and even if it can't zoom in as far as the older one, its resolution is better and its focus is sharper.

If you bought this for the headband/helmet mount, you are going to be disappointed. It has a limited field of vision and what you are looking at may seem very close but is in actuality about 3 feet away from you. Strapping these on and trying to walk around and use them as your primary vision source is just asking for an accident. It's also poorly balanced, forward heavy, and the viewer is only held onto its mount by a single screw. I would never use them like this. That being said, the included padded strap hooks easily onto the viewer via lobster claws and is fairly comfortable.

Lastly, the viewer comes with a charging cord, cleaning pad, a 32gb micro SD card, and a card reader/writer with USB-C and USB-A connectors. The USB-C charging port and SD card slot are located under a rubber cover on the underside of the viewer.

I'm overall impressed with this viewer. It's definitely a step up from my older viewer. So long as you know what you are getting into, you shouldn't be disappointed.

This is a very good camera for the price. It is very light and portable. I can easily slip this into a shirt pocket and not feel the weight. It comes with a 32gb memory card and 2 batteries that are rated to last for 1 hour of use each. The box also contains a small lanyard, USB cable, and carrying pouch. When set to the highest setting (44megapixels), the photo quality is very good, with with good detailing. This of course degrades in low light conditions. The camera is equipped with a built in flash. The user interface and screen is bright and easy to use and understand. The only negative is that the control buttons feel a little flimsy, especially the mode toggle switch which I use constantly to switch between video, photography, and photo review. This is recharged via USB cable, which also allows use of the camera for 1080p livestreaming as well as file downloading. This is plug and play and my Windows 10 system found the camera's memory card storage and had no problem downloading files from it. The camera is also equipped with a microphone and can record passable 1080p video with sound. There's also a speaker built in as I was able to review both the video and its sound directly on the camera. This is a very nice little camera; very light, portable and quite usable.

Easy to insert. It makes a lot of light, at night it is very visible even at a height of several meters. Charging via usb/c

Bright light. I have a dark skin so having a bright light source for video recording is important. This one can be clipped onto the laptop screen and illuminates your face. It also comes with a stand. Only downside- does not have its own plug so if you have a couple of these lights and a mic and something else plugged into the laptop you may run out of USB sockets. Solution- USB adapter.

Since I wanted to solder SMD components for the first time, I needed something to be able to control the work.
This inexpensive USB microscope surprised with good images despite the VGA resolution. The adjustable ring light illuminates the object quite well.
To check, I took a few pictures in different zoom levels.
Only the included tripod is a bit light, especially if you touch the camera with the cable when soldering.
A really good device for the price. I will not regret the purchase.

I moved into an old apartment unit that was already renovated. To know what was happening in the walls, behind build in furniture and that kind of stuff, I needed an endoscope so as not to destroy the renovation. I have owned 2 cheaper units, a USB A type with rigid camera housing and USB C type that is not rigid. I believe they are .3 MP and worked well enough but the value that they brought me was huge, even with trash image quality, needing a laptop or a phone to use it, and the light that made those endoscopes pretty bad. Too much light and camera get blow out and if not enough, then you can't see anything. So I have been on the look to upgrade for awhile. And here I am...K&F Concept is exactly what I was looking for and even better. The light does not make the camera image worse to any extent. The built in display means that I do not have bring a laptop the location, which usually is dirty. The entire camera is rigid which means I have full control over the camera movement. The quality of the images are amazing. The camera is 5 MP vs cheap ones that are .3. And the best part, I didn't even know I needed it, is the side lens. Rather than needing to reposition the camera 90 degrees, I just click a button and BAM!!!And the software side of the product is great too. For the cheaper endoscopes I had to get 3rd party camera software on PC or use a phone app. They are pretty trash. Whereas here, I can take video and pictures on the unit itself. I can rotate the image on the unit for better viewing angle. It just works.Just grab the carrying case and you have all you need to use the endoscope.Love this product.As a heads up, make sure to get camera length that you today need or maybe need in the future. I wanted to buy 3.3ft camera for easier handling and those things are where most of the cost is. I still buy one at some point. I originally bought the 16.4ft one and it can get little annoying when using the camera for something short.

Due to residual current in usb points the light does not turn off completely and emits a glow at night. Only way to stop this is to remove usb plug, which is inconvenient. Otherwise works well
