BBTO 2 Pcs DC 12V 24V Waterproof Car Voltmeter with LED Digital Display Panel and Mounting Plate Round Voltage Gauge Meter with Terminal for Boat Marine Vehicle Motorcycle Truck ATV UTV (Blue Light)

Installed on my race car & it works great. Very happy. Very easy to install

Good unit and great price

Installed in the dash of a 2022 Ford F-150 to monitor voltage levels for car audio. The gauge fits nicely where the cigarette lighter is located with minimal filling. The display is easy to read, not to bright, not to dim. The blue LED color blends very well with the factory Ford blue color of the dash lights. The refresh rate is fast, showing changes in voltage before the trucks computer even recognizes. Well worth the price!

Very good

These do not appear to be waterproof, there is no lens cover or coating over the display, looks like water would easily seep in around the edges. But I've a pair of them-- face up, no less-- outdoors in the rain and weather for 3 months and they are still working fine.Being round they are easy to install into the face of a box with a regular 1-1/8" spade drill bit, particularly when compared to the rectangular ones.The extra included bezel with these is a nice touch.The red ones did not work correctly for me at a mere 5 volts but worked fine with 12. The other colors all worked for me with 5V. (Odd, because red LEDs require the least power)

I needed a volt meter for a power supply, this works just as I wanted it to.First one lasted two weeks, the second one lasted only a week.

Put in Motorhome to have constant readings on House and Chassis Batteries

fact these gauges come with mounting bracket makes them easy to mount anywhere
