EASY
Monitors are easy to use. May well keep me from dead electric vehicles again. That’s a pain the A.

Great for what it is
This is a battery tester that plugs into a cigarette lighter socket. It is the quintessential plug and play device. No app, no registration, no internet.My only complaint is that the display is not back-lit which can make it hard to read sometimes.It doesn't attach to the battery itself (which may provide more readings and accuracy but requires permanent wiring). It also has nothing to do with the OBD (Onboard Diagnostics).
