It is a useful tool
I gave this 4 out of 5 stars
This waterproof 16 foot endoscope camera has a 7mm lens and a CMOS sensor that can be used as a USB device or with an Android device. It comes USB usable and there is an adapter to make it work with an Android plug. There is a CD included for using it on a computer. To use it with my phone I searched for "USB camera" and tried a couple of higher rated apps until I found one that I liked. On the USB portion of the camera there is a dial to adjust the brightness of the 6 LED lights that surround the camera lens. When using it, just slide it into the area you want to see. It can see pretty well in the dark. In the light the picture is kind of blurry, but you can still see the picture. It works good but it is not a high definition camera. Included in this set is the USB endoscope, 1 USB on-the-go cable, a hook, magnet, mirror to see angles, a fixed set, CD of the driver and the manual. It is a useful tool to have on hand. I received this item for free to try in exchange for my honest and unbiased review.
