## Customer Reviews

### ⭐⭐⭐⭐⭐ ACCURATE AC VOLTAGE MONITOR
*by J***M on February 14, 2025*

Purchased DROK Voltage Test Monitor, 2 pcs Plug in Digital Volt Meter one week ago. Works as described. Bought one for my RV and home (bigger RV). Very bright display easy to read. Appears to be accurate as I checked it against my multi meter. Monitor showed 119 volts and multi meter showed 119.2 volts. Time will tell how long they last as the back light is a constant on. Works for my purpose. Based on my initial short experience with this I would recommend.

### ⭐⭐⭐⭐⭐ Perfect for travel trailers and rv use
*by J***O on January 14, 2025*

Simple and convenient way to keep an eye on campground voltage supply

### ⭐⭐⭐⭐⭐ Perfect for my RV !
*by K***9 on August 27, 2023*

My RV has a generator that works great, but just one problem: It is very hard when driving the RV to tell if it is running or not. I mean, there is an hour meter on the dash that clicks every 30 seconds or so, but you cannot see it or barely hear it when driving.This little voltage monitor was just what I needed. I plugged it into an electric outlet near the passenger side floorboard with a 90 degree adapter to make the display face me while driving. Now when not plugged into a power source the display is blank. Start the generator and voila, I have an indicator that is easy to see whether or not the generator is running. Peace of mind that food in the refrigerator won't be spoiled when I arrive at my destination. Is it accurate? It seems so, but I really don't care about accuracy for my specific use. It just works !!!
