Title: Great Product
Review: Bought a plastic battery tester at the local auto parts store and it sucked. I took three readings, back to back, of the same cell and got three different results. Their is a reason glass hydrometers are the standard for commercial battery testing, they work. In Aviation its all we use, and in a pinch I though I could get away with the plastic CHEAPO. This works awesome. Gives great, repeatable, readings of the state of charge of the battery. Price was great, shipping was FAST! I would buy this again in a heartbeat!
