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.
