Title: Overall a Great Value for under $20
Review: I used this at a hotel to try and find the circuit breakers in a meeting room. We have breakers in three different locations so we couldn't seem to figure out which outlet went to which breaker as they were also not labeled very well.Yes, it doesn't beep when the circuits are off.This was my methodology.1) I put the plug in a socket where I didn't know where the breakers were.2) At the most sensitive setting, I would find the correct breaker panel.3) Then I would lower the sensitivity so that only one or two breakers would go off.4) Then I would repeat this with each outlet I didn't know where the breaker was.I had no intention of actually turning off the breaker to make sure as some of the circuits in the meeting room were found to be linked with guest rooms.So overall, I was happy, so now I know which outlets are linked to what and I won't unintentionally overload a single circuit.
