What I love about it is the fact that it doesn't require anything other than plugging it into my iPhone and I have a "working endoscope" which is great. It connects directly to my phone via the "Lightning Connector" and after I downloaded the app and I accepted the appropriate "permissions", the app was on the screen and I had a great view through the camera. The camera has a very useful light that can be turned on/off and adjusted to any available brightness by simply turning the wheel on the box attached to the cable and it works very smoothly and well. The cable has a “slight stiffness” so it can easily be pushed down or through areas, but it is also “playable” enough that it twists through curves, bends around corners, etc. I love that it does too Offers a variety of attachments, from a small mini hook to a mirror and also a magnetic option, all of which I find super easy to attach or remove. The app also offers nice controls. In the app I can "Rotate image, flip image, make black and white and more" and then the controls to capture are simply "One tap" on the appropriate button, "Photo" or "Video" and it will appear in the apps folders, and it's nice that I can then easily download them to my phone's gallery. Overall I think this is a very useful, easy to use, great kit and works great.
