I keep reading bad reviews about this product. It actually put me off buying it. What I had to do in this house was trace all the circuits to their intended switch. I tried other methods and it took forever. The next time such work needed to be done again, I'd buy it. I'm glad I did. It worked the same as shown in some YouTube videos. I have to say it was a very quick chain chase with this one. You just need to know how to use it and have an idea of what you are doing. The socket tester was a plus! Just one of them is around $15-$25, so getting both tools for around $40 was cool. If you want to buy this item and pay too much attention to the negative reviews, you will only regret not having bought it and tried it yourself. also very durable. One problem I've found is that the socket tester has a picture of the lights at the bottom. So you need to figure out what the codes are if you don't know them so you don't search underneath them once they're connected. Also, this tool works great!
