Very sensitive for about any current. Even has a flash light on it.

Easy to use, great value for the price. Turns out the light I was working on wasn’t on the breaker I thought it was, so I would’ve been in big trouble without this little guy!

Simple and works very well. Dont even need to touch the wire, just get close and it’ll let you know if it’s a hot wire. 2 AAA batteries required, not included

The item works well - I knew it uses batteries but on the Amazon site- it doesn't tell what type or how many batteries it takes- then when I received it- IT STILL DIDN'T SAY WHAT BATTERIES OR HOW MANY ON IT'S PACKAGE! Newsflash= it takes 2- AAA batteries. Why wouldn't MR PEN list the type and number of batteries it takes??? I had to open it to find out!

I had trouble getting it apart to insert the batteries but that was probably from not enough strength in my hands. Once I had it set up I was very happy with it. I used it to make sure my mobility scooter charger was working ok. I really like this little tool and I'm sure I'll get a lot of use with it.
