- Amazon CustomerUseful tool that is dependableGood tool that works. Detects hot wires dependably. Not overly sensitive. Good quality but a bit pricey.
- Michael W. ThiesExcellent Proximity Voltage DetectorGood quality, sturdy and very easy to use. It seems worthy of the name and not just a "badge" stuck on a generic product.
