🔋 Universal 12V Electrical Voltmeter Gauge | 2" 52mm | IP67 Waterproof | White Background | Red/Yellow Backlight | Negative Ground Systems | Ideal for SUV, RV, Boat, Yacht, and House-boating Review

The description does not state that the glass surface has a curved (convex) shape. This resulted in reflections from car windows, etc., making it difficult to read the sensor readings. Otherwise an excellent product.

I liked the ability to choose how to highlight the sensor. Mounting on materials of different thicknesses is also easy, since the mounting bracket is made of plastic and can be cut to the panel thickness.

After starting the car, it took 10-15 seconds several times. About a day later it stopped working at all. Wiring looks correct and has been checked.

Used in a 4 battery custom guitar boat. It was used to show only one battery connected to the bilge pump so I knew when to change it. Save me from drowning and death. Great looks, great lights and looks cool. Works perfectly.

The meter was not working on arrival. Troubleshooting in the company. They were helpful but I couldn't return it due to the return window (I'll add I missed it due to work and not the seller's fault). It could be a good product but I guess I'll never know.

The installation instructions that came with the meter were for a different meter. The instructions said 5 wires but my new gauge only had 4. I tried contacting MFG through their website but got no response. I was able to figure out how to install it and it works great.

The gauge fits in the hole where the original was, but due to its plastic construction it will not fit in depth. I had to flip the gauge to adjust the depth. Now the arrow at 12 volts is pointing down and it's easy to see so I'm fine. CHECK the depth for your application versus the depth in meters. Otherwise it works great.

I bought this and the tank level sensor from the same company. It was installed during the restoration of my sailboat's engine control panel. (The engine stop bar has not yet been installed in the photo.) The gauge is fairly accurate and has a nice backlight. It has currently been exposed to heavy rain, fog and seawater for about 3 weeks with no sign of fogging or flooding. Time will tell if it will hold up or not, but for the price it's worth a try.

I needed a voltmeter for my boat to make sure my battery was working properly. I tried several different ones but wasn't satisfied until I found this one. The display is easy to read and looks great on my dashboard. It appears to be very durable and all readings were accurate. I usually go out at night for sunset cruises or night fishing and the red backlight really helps me see the display. Overall I am satisfied with this product and it meets my needs. Highly recommended.
