Love these non-contact voltage sensors. I think the extra safety margin when working with electricity is very important. This tool is easy to use. The instructions describe a number of features that I'll probably never use, but it's nice to know they're available should I ever need them. The LCD screen on this one is easy to read. There are several color LCD indicators that light up as the detected voltage increases. All in all, this is a very useful and easy-to-use tool.
