ESUPPORT Car 2" 52mm Digital Volt Voltage Gauge Blue LED

Nice little gauge it is cheep but I haven't had any problems with it other then the place of it on my motor it always says it's over heating bc the factory temp sensor is right on top of one of my cylinders but other then that and it no liking my amp it works great the gauge goes up if I'm listing to loud music bc the wires are right next to each other and sometimes will make the gauge glitch out and just show up one random number in the middle of the screen. But the little red light still indicates when it hit 212 degrees f I believe.

It was very simple to install. You will need wire, connectors, and an add-a-circuit for the fuse box, but it was simple. It is accurate to my knowledge. For the money, it is great. I use it in a 1999 Honda Accord. The only issue is that you have to use the sensor that comes with it, or it will be very inaccurate. It still works great a month or two later.

Complete junk. The coolant sensor is very cheaply made. Never worked from the moment it was installed. Don't waste your money. The oil pressure gauge never worked either. Stays on 150. The volt gauge works bit it's a few volts off. Not reliable at all. Spend the extra for a good reliable set of gauges. I bought the ProSport EVO series and the are dead on the money. Amazon has turned into the US version of Temu just overpriced. It's hard to find good quality products from Amazon anymore.

Perfect

I ordered an oil pressure gauge, oil temp gauge, and water temp gauge. Install was great, you shouldn't have any issues if you know what you're doing. The gauge faces are easy to read during the day, and the warning lights are really useful on the track. The only complaint is they don't have an ability to dim and are slightly too bright at night. They seem accurate, and at least for water temp, it matches the readings of my secondary sensor. For the price, these honestly can't be beaten. The only issue I had, and the reason I rated them 4 stars is that the oil pressure sensor has failed after two weeks. On cold start, it reads 150psi for about a minute and then goes back to normal. I was able to process a replacement through amazon to fix this issue, but who knows how long these will last. These are great tools, and actually helped me solve several overheating issues before they became major problems. I'd recommend these to anyone who needs gauges but has a budget in mind. They are at least 80% as good for way less than half the price.

I had previously bought a tach for $40. It quit after less than a month. But I had bought it more than a month ago so no return. I decided to buy this one thinking that for the price it would be a waste of time. Man was I wrong. It's been about 2 months and not a single hiccup. I was so impressed I bought another one for my other truck. Very pleased with this company so far I'll probably buy a few of the other guages they sell. Do I need them no but for the price why not

I've been running this for about 6 months now in a 1993 Geo Metro. The sensor is mounted in the thermostat housing, directly across from the sensor for the "dummy" temp gauge standard for this car. I thought it was working fine, then I noticed something funny when summer arrived and I started using the air conditioner. As soon as I turn on the AC the temp gauge reading jumps: about 10 degrees F with the blower on 1, 20 degrees with the blower on 2, etc. If I turn off the AC the reading drops immediately. I don't see how the actual coolant temp could rise and fall at the thermostat housing instantaneously. Since the "dummy" gauge doesn't actually show temp, I don't have anything to compare this gauge to. I was considering using 2 of these in my truck--for coolant and trans--but after this experience I'm hesitant.

Been out in the weather for years and still works great
