There is only room for one ignorant person on the job and I have this position filled. This product allowed me to eliminate this issue. It did a great job assisting me at determining which wires were which in separate rooms. It did it's job well. I liked that it continually beeps unlike others I've looked at that would only beep once which could leave you unsure in some situations.

This device works well enough, but when tossed into a tool bag, the power button can easily be inadvertently turned on. Wish it had a slider switch or a recessed power button.

a very good item you.

Well, it works. I was able find wiring connection about 60 feet apart through walls and underground. Unfortunately, take serious heed of the warning not to connect to live wire. I accidentally did and now the thing is dead. I would buy it again.

I hac a CT20 that was stolen and did without one of these for several years. Not needed very often but they save some walking and getting up and down. This one has some extra features besides being lower in price. The continuity detector has 3 levels; less than 150ohms, rapid red & green flash and beep; 150 to 2.9K ohm, slow green flash & beeps; 2.9K to 5.3K, fast red flash & beeping. The CT20 would say continuity at 2K & less only. These have a GMA100ma fast blow fuse that might protect it if you forget about a live circuit. It has a 5yr warranty and claims to be 6ft drop tested. Thats good, I, myself can't pass the 6ft drop test anymore. This one does not come with a little bag to keep it in, so off to the dollar store.

Took out of the packaging, it worked once and stopped working after that. Unfortunately, used it for the first time a few months after it was purchased and outside of the return window

Continuity test without the need for long wires. Helped me solve some wiring issues with my light switches that were far away from each other. Very useful tool!
