I liked the price and bought this. It really never operated to my satisfaction. WIthin a few weeks the dial to power it up and adjust its sensitivity just completely snapped off. The dial could never be put back in place and this 'supposedly' professional tool is now only useful in amusing my toddlers. If you're a professional electrician, get a voltage detector from a company that manufactures professional quality.

After almost killing myself cutting a live 240v. line under a house I've been looking for something like this.
It detects current even when the appliance/whatever isn't on! I just used it to trace non-working lights on a camp trailer and I never would have been able to figure it out without it.
A terrific tool, I recommend it highly!

The sensitivity of the sensor leaves some issues, it either beeps for no reason because of over sensitivity. It adjusts up and down but is very tricky to get it dialed in.
