Bests & Worsts Reviews from Amazon

This is a quality looking product and I am giving it five stars because the price is so low, it is good as a general-purpose IR thermometer, and so it has so many uses. I do want to correct someone who said that it responds instantly. It is more like a 1-2 second response to change color, so that is far from instant. You cannot quickly scan things. It pales in comparison to a thermal camera. In fact, I am adding a photo from a $250 thermal camera that works with an iPhone 5 to show an example of insulation failure on a high wall in my house that I would have zero chance of finding with the Black and Decker. My advice is that if you have no IR thermometer, want one, and are ok with the limited temp range of this one, then get it. But if you will quickly waste your time compared to a thermal camera.
