Teslong Endoscope Replacement Cable with Light, Dual Lens Inspection Camera 5.5mm/0.21inch Waterproof Probe Compatible with NTS500, NTS300(10FT)

Great product

Looks like the original. Works well

There was a guy at my company a while back who swore this camera was the reason he was so successful. The dude was condemning furnaces left and right with teslong photo proof on every single one. So then I took a heat exchanger class and picked up this camera, then all of the sudden I'm condemning furnaces too. I'm weaving in and out of heat exchanger chambers with ease and finesse, finding a popped islet or crack on almost every heat exchanger I look at. Buy this camera, it's very easy to use, and will pay itself off quick.
