Advantages1. The camera is small and can be carried easily.2. The battery usage time is long.3. Easy to select menu.4. It is waterproof.6. The price/performance is good.Disadvantages1. In 1080 60fps shooting, the pixels are coarse than expected, and the sharpness of the screen is poor. 2. The zoom function is meaningless because it is not an optical zoom. Conclusion: Good for beginners to use.(After using more, I will add a testimony.)

For this price this is the best camera you guys could ever find! This is the perfect camera to take out for Snapshot, small.. battery last more than regular point and shoot . Absolutely impressive

What an incredible battery! Whether it's to power your camera... a small LED light (I used it on a USB-C folding panel, nickel) or any accessory on a shoot (of course it charges a phone) it works really well! K&F becomes a real reference in this field

Can't say anything bad about it. Works amazingly will make soldering small chips much easier and works plugged in or unplugged on battery. Photo is on battery in a dark room but forgot to pull the screen protector off. Will definitely purchase from again should I need another down the road.

I love this little thing. It's small, comes with a few sample slides, and only needs a AAA battery to power the LED light. A nice soft carrying case is included as well. The function is super simple with a single button to toggle the light on and off as well as two knobs for zoom level and focus.

Super fun and easy to use. Would recommend.

Really great part. It's the second device, before that I had a similar one which I unfortunately broke (my fault).
It's almost the same, only this one has a slightly more robust housing and stepless LED brightness control.
The resolution is really great. As an example with a banknote, because it has many small details.
I have the camera to make work easier. The camera can be guided better through the semi-rigid cable than the cheaper USB cameras with the flexible cable.

Positive points:
- battery exchange possible with a bit of skill
- infinitely variable brightness adjustment possible
- good picture quality
- SD card included
- video recording possible
- dual camera view
- useful settings in the menu
- lithium battery can be charged via power bank

neutral:
- the charging port and the SD port could still be protected with a rubber cap, since the device is certainly often used in a dirty, dusty, damp environment.

The cable is 5m long, but I can't imagine ever needing the whole 5m, let alone being able to push it that far, especially around several curves I think this will be a bit difficult for anyone who has ever pulled in cables know what i'm talking about. The case has rubber plugs on the side, so the device could survive one or the other higher fall.

The case opens easily with a small Phillips screwdriver, and the 18650 lithium-ion cell can be easily replaced should the battery fail, or the cell can be replaced with another with a higher capacity.

Genuinely impressed with this little microscope. I'm absolutely stunned at the image quality for such a small cheap device. Highly recommended for anyone with kids who are interested in science, heck, even for yourself.

It comes with a lot, more than I expected (I admittedly did not read the listing as close as I should). The microscope slides are an excellent touch, giving you something to practice with right off the bat. You have a dial to magnify the image and a second dial to focus, and a built in light. It works so well. I did my best with a picture, but it doesn't do it complete justice (that blemish is on the slide, not the microscope).

I love the portability of this one and the versatility of being able to use it on many surfaces/objects. As an avid stargazer, I'm appreciative of the functionality of this one at the micro scale. Some pro tips for use, I noticed that it seems to be a mirror image, something I'm used to with a reflector telescope. So you may need to move the microscope down for the image to go up. Keep in mind that this magnifies big time, so tiny slight movements go a long way. Also, don't try to completely unscrew the battery cover screw. It is actually very short and I think is only on there for added protection as the battery cover itself seems to lock in securely.

Looking at the cloth it came with and the instructions were pretty wild. You can see the fine weaving of the cloth and the red/blue/yellow dots on the print. Very cool stuff, hope you enjoy it as much as I do.

It works perfect. It's just way too small for me to see it to use it for anything that I need to drain my battery pretty quick.
