🚗 Waterproof Car Voltmeter with LED Digital Display Panel and Mounting Plate - 2 Pieces, Round Voltage Gauge Meter for Boat Marine Vehicle Motorcycle Truck ATV UTV - Green Light - 12V 24V DC Review

Installed in the dash of my old Ford tractor with a 6vdc positive ground system. currently. Works great, clearly reads 6.3 volts.

Pretty accurate but too bright Need a tinted film on the display. A piece of yellow pill glass above the display dims it to the desired level.

Put one on the boat and one on the golf cart. Both work perfectly, I drilled a round hole and mounted it on the dashboard. Easy to connect and weather resistant. I definitely recommend this battery indicator.

Arrived with a damaged screen. Very obvious such poor quality control. I would return it, but I'm sick of returning Revain crap that doesn't work properly or is damaged. Looks like Revain is AliExpress's new wishlist!

I installed one of these on my Kawasaki mule to monitor the output voltage. Seems pretty accurate. The LEDs are bright and easy to see during the day but almost too bright at night. Overall I like it and it works well so I would buy it again.

I made a bad choice with this replacement LED voltmeter. I have used another manufacturer with much better visibility in the past. The photo shows that the LED segments are too "white" when off and on, they are very difficult to read. You will be returned for a better product.

The manufacturer did not explicitly test this before shipping. On a 12V boat battery I get readings that are 0.3 volts lower than what I actually am. For example, the open circuit voltage measured with a professional multimeter is 12.6, as expected. Measured with this model gives me 12.3. I'm going back and looking for something more specific

I bought two of these to monitor the voltage on my trolling motor and yak power system. The plastic tension nut that secures the blocks from the inside of the case doesn't tighten and constantly pulls the strings, allowing the digital displays to keep spinning. Very frustrating. I could probably stick with Gorilla, but I don't have to.

Quick and easy installation into Chevy Avalanche plastic window frames. The mounting plate that came with the gauge was not used. Works perfectly! No more guesswork, like a factory gauge on a dashboard, sometimes high, sometimes centered. Estimated cost of factory gauge repair $200 plus round trip shipping and no truck use for 2-3 weeks. It was the best decision! I installed the gauge in less than 1/2 hour. And it looks great too.
