Looks like a decent nail finder. My main criticism is that I am always skeptical of items that are not in their factory sealed packaging and/or items that do not have clear signs of being new. For example a protective screen for the lens / display or similar. Did I just receive a used/returned item that I paid new prices for? Found the rafter in the ceiling easily enough, ran some quick tests in AC mode, the only way I got in was when I scanned the external cable to the unit. Metal mode seems to work decently enough.
