Review on IZTOSS 12V-24V Universal LED Display Digital Voltmeter with Low Voltage Alarm for Car Motorcycle Auto Truck - Measure Voltage 7-30V by Richard Muncy

Readings worked like clockwork. The only problem is that it's hard to see in the sunlight. I installed it on my boat and it was difficult to see even in a shaded area when the boat was on a trailer. I will try in the water with a bimini top that will provide shade and update. Probably more suitable for the car. This gave me accurate readings. The screen was a bit blurry. updated. You can't see anything when the lid is open. It's probably better suited for a car. I can't see anything in daylight unless I fold my hands.
