I have the Vantrue E3 (the 3-camera version, an added interior cabin camera). It's the best dash cam that I have tested out of about 6 different ones. I REALLY liked the E3, and it appears as though the E2 is the same, minus a camera. The voice control is really good, just say stuff like "Show Front Camera", "Show Rear Camera" and more. Really happy with it.

It's weird we can get phones with better cameras for about the same price, but nice dashcam

You didn't mention if it is battery or capacitor powered. Even if it's only to safely store recordings on shutdown most have one or the other.

Does it delete videos automatically once memory is full?

Redcar, you must be from north east, mbro here :-)

It's called a boot, not a trunk!!
