I needed a way to monitor my boat's batteries when it's at anchor over the weekend and working with electrical accessories. After looking at some expensive batteries. Surveillance systems with fancy displays that require complicated installation. I decided to give this inexpensive device a try and found that I couldn't be wrong at the price. I found it works great and is as accurate as an expensive voltmeter! Now I can leave it in one of my secondary outlets without being connected to shore power and always know exactly what the state of charge of my home batteries is, and I can even determine the exact power consumption of each element that is switched on. The best return on your money. I love it! Ben Salish Sea
