I have always wanted to get one of these to make my life easier and I finally decided to get one. I do a lot of wiring in finished houses and having this makes it so much easier. I use cable snakes to run the wires through but being able to see inside the wall makes it 10x easier! You can see all the obstacles and the best way through and what the wire could be getting caught on. The whole thing comes in a nice waterproof hard case. There are 4 LED light that are adjustable with the push of a button, it can be turned off or turned all the way up to be super bright. Having it on full the end does get hot, not enough to burn you but still somewhat hot. there is also a flashlight on the body of the unit. The image is 720p and picture clarity is excellent. The other end of the cable screws on for a secure connection. The cable is rigid, and you can bend it any which way you want. You can attach 3 different attachments; a hook, magnet and a mirror. The magnet is tiny but decently powerful to be able to pull back items. I do not really see the purpose of the mirror, I guess to see something on the side down a pipe or something. I do not know how you could measure with it and it's also a little difficult to see with it. I love the fact that you can record video and take pictures and that it comes with an 32GB micro sd card. It also comes with a USB cable to charge it but not a charger, which is fine because I have lots of USB chargers. It has a super easy to use interface. You can rotate the image around, so you do not have to twist the cable to get the image right. Overall, I shouldn't have waited to get me one of these, the possibilities are endless.
