Does it's job. I had just installed a new solar set-up on my travel trailer with a couple of Trojan batts. We will occasionally dry camp for a week or two and needed to make sure everything was working together. Numbers always matched my meters and showed when I just had a surface charge. When we spent 12 days in the redwoods, with about an hour of clear sun a day, it showed my batts were about dead after 10!
