I LOVE this little borescope! It caught my eye immediately because I was thinking how handy it would be to have one on hand when I did honey bee "cut-outs" (that is, rescue bees that have taken up residence in the walls of someone's home. The first step is to figure out where the colony is). Then I saw this 'scope was made for kids. Well, I'm a 67-year old "kid" that is incredibly impressed with her new toy! There is no need to spend a LOT more on the "adult" version since all I want to do is feed the flexible fiber-optics of the 'scope into small holes in wood or drywall to see just where some rascally bees are building their honeycomb (it isn't always right next to the entrance they're using). This boroscope produces sharp, clear pictures within its stated range (2-10 cm), and the light it produces is strong and adjustable. You can zoom in and out, too. With a mini SD card you can take photos and videos. I tested it in one of my bee hives, and plan to be taking lots of wonderful pictures. Its screen size is 2.4." Its field of view is 70 degrees. And its charging time is 2 hours, with a 2-hour battery life between charges. It uses a Type-C charger (fast types not recommended), and a C-to-USB cord is included (the plug end you need to provide; it can take up to 12V). Resolution is 1920x1080. Sure, the professional borescopes may have more bells n whistles, but you get a lot for your money with this little green "kid's" borescope (plus a pair of plastic kitty cat ears above the screen - grin).
