## Customer Reviews

### ⭐⭐⭐⭐⭐ Economical Ground testing apparatus
*by S***K on February 7, 2016*

This unit works as advertised and if T.S.A. or Customs would stop stealing the batteries that are supposed to be shipped with it, you would be ready to go right to work. The unit requires 6 AA and 1 12V (23A) sometimes seen as 23AE-12v which are available locally or through Amazon

### ⭐ I bought this product less than a month ago and the LED screen already went out
*by A***H on March 30, 2021*

I bought this product less than a month ago and the LED screen already went out and they won't take it back very frustrated.
