Bests & Worsts Reviews from Amazon

Here is the deal OK? I have gone through several NC testers over the years. None last very long with heavy use. But the tool is so valuable for my job, that I have to buy a replacement whenever one breaks down. Here is my experience. Greenlee - the worst. I went through 3 of these and will never buy another again. Klein - sucks too. I have gone through 3 of these as well, they last longer than greenlee, but break down all the same. The red and green light is great, and operation seems smoother, but who cares if it breaks after 6 months? Milwaukee - The best so far. I have gone through about 3 of these as well. They last the longest between these three brands, but they still die after nearly a year of heavy use. The alert sound is louder and the LED light blows the competition out of the water. It is ideal for looking in the boxes, attics, and other dark environments electrical wiring dwells and where the tester will primarily be used. Final tip: If you plan to use this on the job, buy it from home depot and keep the receipt. If it fails within 3 months, return it for a brand new one at any home depot. It also has a 2 or 3 year warranty from the manufacture, which I have not tried using yet. And find a gentle place to store it. My tool bags are most likely the culprit of damage to these delicate electronic sensors. They should last quite a bit longer if stored in a protected location.
