Viofo WR1, skip this one for now.

The WR1 is a smallish dashcam, with overall good video, but it has some problems.
The recorded audio is very soft, almost worthless.
The red and green led that indicate proper operation, are very dim.
You just can't see them in normal daylight.    Since the WR1 has no screen, it would be easy to overlook a malfunctioning cam.

It doesn't look like the problems will be fixed on the current models via firmware updates, since they've issued several updates since this camera has been released.

It's a shame, the WR1 has been reliable in a few months of use, but I'd skip this cam for now.

Here's a sample of the  recorded audio level, compared to a Mobius Dash/action cam.
