It is a very good voltage detector.
The beep is very loud, excellent!
This item is funny to play with as an old kid.
It beep sometime when place next to a mobile phone.
It also avoid cutting a neutral wire by mistake.
It confirms the doubt whether it is an energized the circuit or not.
unfortunately it does not detect through walls.
It will not beep until you put it right against a live wire .
Battery replacement is difficult as the resistance sensor gets twisted when inserted in the white non-contact plastic casing. So use good battery!
Safety comes first when using electricity.
Never touch a live wire unless main is shut off( turn off ).
