Teslong NTS500B - 5 mm 5 metres

5mm Dual Lens Inspection Camera, Teslong Borescope with LED Light, HD Industrial Endoscope, 5" IPS Screen, Waterproof Video Scope Camera, Flexible Cable for Home/Automotive/Pipe/Car/Wall(16.5FT): desertcart.com: Industrial & Scientific Review: Handy tool that works well - After using this tool on multiple occasions I would highly recommend it to anyone needing to look into or retrieve items from narrow spaces. The diameter of this camera is very small and that helps in reach into areas that others would not be able to. The description says the camera is 5.5mm in diameter. I actually measured the diameter to be closer to 5.75mm with a micrometer but if the bezel that is threaded onto the end is removed then the width is only about 5mm. I got this camera to help me get a look inside the wall of my bathroom where there was water damage. Then when I didn't find anything leaking in the wall I used in to look inside the drain pipe of the shower and was able to see signs of water seeping in through the weep holes from the mortar bed under the tile floor which suggested the problem was water in the floor and that turned out to be the case. Later the water stopped coming out of the shower head. I eventually figured out the problem was with the shower hose and used the camera to verify that the lining of the hose was breaking down and causing the hose to get clogged. Most recently I was replacing my car battery and accidentally dropped a nut into a hidden area under the battery holder. The wire to the camera is flexible and will also to some extent hold its shape after bending it so I used that to make it a bit more curved at the end and was able to insert it under the battery holder through a narrow gap, see the nut there, and then with the magnet attachment I was able to retrieve it. The magnet is very small but was strong enough to hold on to the nut very securely while I pulled it out. Since there is both a forward-looking and side-looking camera I haven't used the right angle mirror yet but the hook attachment would be handy for retrieving things that the magnet cannot. I like that this camera comes with its own display rather than relying on phone software that may become obsolete over time. For the price and size I've been very impressed by the image quality and and the light illuminates the subject well. Review: More uses than you think - This is a quality endoscope, I originally purchased to run in duct work to see if there were any leaks or openings. Didn't work that great for that as the further you insert the cable, the more control you lose. You can kind of turn the cable but it doesn't work that well when more than 3 feet of cable is extended. I did also use to check under my deck to see if there were any entry places in the house foundation to see any way for mice to gain entry. Also inside to see any evidence of rodents. Also used inside of ductwork to clean with a shop vac. You can insert the scope and also the shop vac end to make sure you get all the dirt you can see instead of just blindly vacuuming . I am planning on using to see in hard to reach places on my pickup frame so I can more precisely coat with oil to stop rust. It really is handy, there are more uses than you think. One recommendation for the buyer I ordered the 16.5 foot model, as mentioned, I don't see any way I would accurately use all 16.5 feet of the cable It just is not controllable when you push that much cable into whatever, So now I have a looped up cable that is always there, I may use some day but I am not sure for what, consider a shorter cable. The picture quality is very good, the light and the smallness of the camera end is very good, I would not go bigger, it will limit what you can use it for. The side light is good, but then again, you can't really turn the cable and side light where you want after 3 feet or so. I really do like the product, and highly recommend, The extra cable length ad lack of control are only minor inconveniences.
