Bests & Worsts Reviews from Amazon

The Zircon e50 StudSensor failed me on two fronts. First, the e50 incorrectly marked studs in the wall which I needed to locate for hanging new kitchen cabinets. The e50 would identify a stud with its fancy projected red light arrow only to have that area of the wall be hollow. Out of 9 studs located, the e50 was only correct on one. As a result, I used a drill and wire coat-hanger to find the rest of the necessary studs. I thought I bought the e50 to avoid wall fishing? I tried both sensor settings on the e50 without luck. Second, the e50 failed to identify a live wire in the wall. This error was the most costly. After plunging my drill bit into the wall below the kitchen soffit I was showered with sparks and smoke. The drill bit had a chunk burned out of it and I had a damaged wire in a difficult to reach area of my kitchen. Striking the wire cost me an extra day of labor to acquire the parts and effectuate the repair. The live wire sensor simply did not work. I had no indication a wire was in the area and was relying on the e50 to provide notice. I purchased the e50 from Amazon and it arrived quickly and without damage. The ergonomics of the e50 were pleasing as I tried desperately to locate a stud. It tracked smoothly across the wall and the indicator arrow was easy to read. However, the e50 failed to operate as an effective stud sensor and failed to operate as a live wire detector. I cannot recommend this product.
