These two cheap dashcams have very similar discreet design. Both use the same Sony IMX323 sensor, don’t have display, Wi-Fi enabled.
Blueskysea B1W uses a super capacitor, Xiaomi 70mai uses battery.
70mai supports voice control (useless IMO), B1W does not.
Recently I've got both of them, compared side-by-side and want to share the results.
That's how they look on the table (pic1, pic2)and installed(pic3, pic4).
70mai is slightly bigger, however much more noticeable because of the gray color. B1W is totally black.
Built quality of B1W feels slightly better than 70mai, especially mount.
Both dashcams have the latest firmware - v1.06.180528s for B1W and v1.0.6 for 70mai.
Not a big deal for me but B1W audio quality is very poor.
Now to the main part – video quality. Files are untouched.

I’d say that 70mai provides better quality. Pay attention to the color of of the car in left lane. In fact it was black.

70mai
B1W often produces bluish tint, with is not good for dash cam.

Obviously B1W overexposes.
Also I’ve got CPL for B1W (pic5)
The build quality is good.
Here are video with and without CPL

In my opinion CPL just makes bad video quality even worse.
I’d say that 70mai provides much better video quality overall. And it’s a pity because B1W has wider and faster optics, better mechanical design and supercaps.
I hope that Blueskysea will fix video quality in future firmware updates.
