### ⭐⭐⭐⭐⭐ value for money

great product recommend to anyone

### ⭐⭐⭐⭐ Probe too big for me, also no Audio tone
*by B***R on February 22, 2023*

Exactly what I wanted but the probe was too big for the tiny wires I would use it on. It also didn't have a audible tone indicator like some references said. For these reasons I sent it back. It did seem like a decent unit for the $.
