Easy to use
I like that it's easy to use by just plugging it into the lighter. Verified that my car battery was going bad so I was able to get it replaced before being stranded in the cold.

It works great
It's good to know exactly where your battery is rather than guessing, thanks...

More accurate than similar devices!
Excellent way to keep tabs on battery and alternator health,
more accurate then common 3-digit meters.

A good product and a good value
Monitor your charging system while parked or driving, so you can catch problems before your battery fails.

Meh
It's okay. You have to rub it around to get a connection...it will start out in the red and work its way up the color chart.
It's not exact, but it's nice to have if you're concerned about your 12V power source reserves.Read full review

Bright blue light
Bright blue light is on when it is plugged in. OK for day but a distraction to me at night.
