I have had two of these, along with at least six or seven other volt meters (both consumer and professional grade). Within its obvious limitations as a line-powered electronic device, I am quite happy with the LCD voltage meter for the price. My two consistently read about 0.2 volts above what the professional self-powered multimeters say. This is no problem, as I just do the offset in my head. Occasionally the display will go blank, and I have to jiggle the meter in its 12 volt socket, but this is not a major thing either. Incidentally, autoparts stores sell similar meters for the same or higher prices, and those also read a couple tenths high. I have found the the cheap self-powered handheld multimeters on the market now actually have worse accuracy than this 12/24 volt LCD voltage meter.

This product is an excellent way to measure your remaining battery power and voltage when dry camping in your RV. As with many RV's, my "built-in" power center voltage meter is grossly inaccurate-it shows green status, with no gradients, right up to the point where I have zero power remaining, the lights shut down, the pump dose'nt work, and I am out of power, having to start the generator or engine. Very inconvenient if you loose power in a campground late at night, or early AM, esp. when cold and need the furnace! After I bought one of these, I was able to measure remaining power very accurately in my house batteries, by also downloading and printint out a voltage conversion chart (i.e. 13.4v=100% remaining; 12.8v=60=70% remaining; 12.2 volts=30-40% power remaining, etc..) and taping it up in a cabinet next to the power outlet where I test. I highly recommend this product, it can save you a load of inconvenience if you dry camp a lot, like we do!

I have had this item for approximately 5 years now and it continues to work just fine. I have mine plugged in to an upper socket above the windshield of our Class A and am able to monitor the House batteries at all times. The only thing I have noticed lately is that all the LEDS are on all the time. Doesn't bother me because it reads very accurately.
