### ⭐⭐⭐⭐⭐ Good value

### ⭐⭐⭐⭐⭐ Magnet detector not voltage detector
*by A***Z on November 2, 2025*

Excellent magnet detector it helps me to trouble shoot solenoids, for people who doesn’t know this is not a voltage detector.

### ⭐ Don't waste your money
*by R***T on November 8, 2025*

Poor quality all around. Package a pain to open, battery compartment opening very difficult to figure out and, oh yeah, it does NOT detect any magnetic fields. Poor value, does not function, difficult to use. Flashlight works ok, but doesn't stay on unless you keep your finger on the button.
