DRAW TITE 40376 Circuit Tester Review

Using this tester, our team found that it quickly and accurately identified any electrical issues in the circuits we were testing .The LED lights and audible alerts made it easy to see and hear the results. The compact size and durable construction were also a plus. However, it can be a bit difficult to use in tight spaces due to the length of the cord..

Does exactly what it promises. The only problem is getting used to the way the tip of the tester's needle pierces the wire to make contact. If you're not careful, you can end up making a whole wire cover that can let dirt and water through. So if you make a whole one, be sure to wrap it in duct tape to prevent this from happening.
