    I Really like this product, it saves tons of time. instead of switching breakers off and running around the house to see what is off you just plug in the receptical devise in any receptical and then go to the home or business service box with the hand held senser and it will alert you to the proper breaker!! GOOD JOB

    Works perfectly when you follow the instructions!

    I love this tool. Best 30ish bucks I’ve ever spent, because the wiring in my house (which was built in the 50s and renovated in the 80s) is sporadic at best and utterly idiotic at worst. Example: One breaker controls the garage outlets and lights but also for some reason it controls only the FAN and HEAT LAMP in the master bath… Go figure, i would guess THAT wiring was done in the 80s when nasally administered substances were ever so popular 😀 . Anyhow, this thing is great for finding out which outlets are connected to which breakers. Worked fast and 100% accurately for me! I love Amprobe, I didn’t even know the company existed until I bought this product, but now they are my absolute first choice when I look for any electronic testing devices!

    ✔ Yes, I recommend this product.

    ✔ Yes, I recommend this product.
