"So far I have used this to find a leak that meant I haven't had to dismantle a whole panel to find it!! Was able to find some wiring without taking down a whole partition wall first and as a bonus a cats favourite toy that had been lost!!!! So far this borescope has saved me both time and money. Whilst this is a basic model, the screen is clear and the camera gives a really good picture, the camera arm does takes a little practice to get used to moving it around. For the price you can't complain. Certainly a purchase I wish I had made some time ago."
