Found the tool to be very useful, as you well know you can have voltage, but will it carry a load , just a push of a button and that question is answered, I like that it can let you know if it has power or ground by the color of the light, and what if any a voltage reading, so much is answered in a short time, being able to plug in from both ends makes it even more useful, a great tool and a great price!!!! Wish it had a TOPDON Blue cord just saying 👍

Very Impressed with the CT100
Great tool! I have other Topdon products, and they have always been great tools. The CT100 is an all-in-one solution. I appreciate the quality and performance.
