### ⭐⭐⭐⭐⭐ Easy to use and works really well
*by K***R on 7 December 2025*

This device is GREAT. Put the two AAA batteries in (came with it). I also watched the video. Used it today as I needed to replace a basic light switch. Came in VERY handy. I also have been watching my dad use his old two-wand test meter from the 1970s. This is SO MUCH EASIER and it works!!!!!! When the line is hot, the red light goes on and you get a warning noise. If the line is cold the device light remains green. Just told my daughter to buy this for my dad for Christmas.
