Don’t trust a no result

Induction tester, lets me know if there is at least 70v to at most 1000v. Batteries are fresh and always live dead live test before each use

Batteries are included

Would Recommend

I like the the size of it it’s very convenient to store it anywhere without taking up space. You can carry it on you with out it being in the way. Also I like the feature of not being used after 4 minutes it shuts off to save battery.
