Review on 12V Car Digital Voltmeter Gauge by Peter Green
Slow update rate (5 seconds)
Easy to use and looks good, but I've tested it myself on several systems and it takes a long time to update. It basically updates the screen every 5 seconds and only updates when there is a constant voltage drop. When my voltage drops from 14v to 9v, this voltmeter stays at 14v. It's basically useless as my car has enough time to burn out before even considering an upgrade.
- Comfortable to use
- Crumpled packaging
