This endoscope works great. My only misgivings about it is that the program is not installed on the computer. You need the disk in order to make it work. Disks get broken, scratched, or lost. Other then that it is super easy to use. Just put the CD into the CD drive of the computer, plug the endoscope end into a USB port on your computer, and you are ready to delve into the deep. Great for drains and even car engines. It is waterproof. This should not be used for checking out the inside of a human though. There is 49 feet of cable so you do not have to worry about getting your computer to close to the backed up sink or getting it greasy under the hood of the car. I have done a video with a more in depth review and showing the endoscope in action.
