## Customer Reviews

### ⭐⭐⭐⭐⭐ Good water gauge for camper.
*by S***B on March 16, 2025*

Got two of these (black on and a white one). Used it with a sending unit to monitor the water level in my camper's water tank. Works great, instructions were easy to follow. Online tutorial videos can be found to make life easier. Only complaint is that is almost no lip/flange around the edge of the gauge which means the hole you make has to be exactly right, there is no wiggle room at all. Other than that, it's a good product.

### ⭐⭐⭐⭐⭐ Good Quality and easy to install.
*by F***D on March 18, 2025*

I bought this for my Diesel Tractor fuel tank to match the sender I bought. Works great with the correct sender. Weatherproof. Looks good.

### ⭐⭐⭐⭐⭐ Accurate and Customizable
*by R***1 on November 1, 2024*

Works great in my Sprinter to read both the fresh water tank and grey water tank. The reading on each tank is selectable through a single 3 position rocker switch ON>OFF>ON to power the gauge and select each tank signal. Some people stated they had problems understanding the programming since there are not instructions, so here they are:PROGRAMMING INSTRUCTIONS1) Put the gauge in programming mode by pressing the black button on the back and hold it for 3 sec, or until the backlight flashes, then release.2) Immediately press the button again to cycle through each of the available calibration options. Each push of the button moves the needle on the gauge from Empty to Full to indicate which range is selected. This programs the gauge to match the type of sensor you are using.NeedlePosition E - - - - - FE 0 ~ 190 ohms1/4 0 ~ 180 ohms1/2 10 ~ 180 ohms3/4 240 ~ 33 ohms (The default setting from the factory is: 240 ~ 33 ohms.)F 240 ~ 30 ohms3) Once the desired range is selected (by advancing the needle to one of the above ranges with each press), leave it alone and the gauge will timeout and go back into Operational mode.4) In Operational mode each press of the button cycles through the selection of backlight colors available.
