This has been one of the most useful tools I never knew I needed. Since I got it, I have used it nearly every day. Instead of a mirror I now grab my bore scope. I can take a picture or video to show everyone what they can't see. It has helped me see the health of small and large motors on the inside! I used it to explore a hole inside a wall that my kids were dropping things into. It has been worth the money many times over. At first I could delete individual photos but now I can only delete all at once. That is my only complaint. Not a big deal. Overall I love it.
