## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good monitor
*by T***1 on June 6, 2016*

Works well with my surge guard. Nice to see voltage and current.

### ⭐⭐⭐ Good product
*by E***J on February 23, 2015*

Product work as advertised. Remote cable too long, adding a shorter one would be an improvement.

### ⭐⭐⭐⭐ Quick Shipping
*by J***L on August 20, 2016*

It arrived in three days. Perfect arrival time, I'm leaving in two days to camp where there is only 30A service. This will allow me to monitor current flow. The cord is a little unwieldy. I left the tie wrap on and pulled one end loose from the inside only what I needed.
