Straightforward product, does its job well. One small issue is the cable is not very long. So, for my trunk mounted battery, I cant bring the meter all the way to the dash to see it. I set it on the trunklid and was able to view it in the rear view mirror, reversed, but still understandable. It takes the guesswork out of diagnosing the charging system and battery state.
