    Product is great! When it arrived and I opened it the product packaging had been previously opened and the 9volt battery had been smashed and was not usable. There is no way that they didn’t know that the package was damaged before sending out

    With the adapter accessories (sold separately), you can chase down which breaker controls the outdoor flood lights and coach lights. I wanted to add a photo cell so that those lights would come on a dusk and needed to see what breaker was controlling those lights. Very nice tools!

    Since I’m not a certified electrician this device has allowed me to trace which outlets correspond to the the correct breaker. It comes with instructions and we also have access to YouTube. This is a great purchase for homeowner diy or an electrician.
