green light

its green light is when it senses a hot connection. so you just put it on the place you want to check and if there is power running though it it lights up. battery stays inside it too.. not cheap.

must have

this is a must have item for a tackle box. we ice fish here in Wisconsin and with mittens on its too hard to tell if things have power running through it when your using propane. This works great.

if you don't turn it off you'll kill the battery. use it everywhere. real useful.

it may be corny, but my boss gave these away fro presents last year and I've actually used it a lot. My dog ate the last one so I looked on line and found westside. This product is really a good one for around the house.
