More than I can review. ;)
Gearbest.com sent this dual channel dashcam for review. Thank you @GearBest .
This camera is available here:
http://www.gearbest.com/car-dvr/pp_178985.html
This is the first Ambarella A7LA70 based dual camera dashcam for me.

Front and rear cameras both are 1080p @ 30fps.
It has built in 1GB internal memory that can be valuable when you forget to put SD card in.

Box is generic like most others I received.
Package contents:
1. Front Camera
2. Suction mount for front camera.
3. Rear camera with a long ball mount attached that rotates. The mount folds in middle to provide more mounting options.
4. Car charger with proprieratory plug.
5. Rear camera min USB cable but the tips are unusually longer than regular mini USB plugs. Haven't measured but it looks very long and should be enough even for vans.
6. miniUSB to USB cable for computer.

Physically, front camera looks a lot more like G90 but the body is thinner/slimmer with similar lens module and height with a chrome ring on the bottom of lens housing.
It has a big 3" LCD screen.

Top ports: GPS AV Out, mini HDMI, mount, 5v power port (this is not the regular usb, it's proprieratory plug), AV Out/USB.

Left of LCD: Menu, Up, Down, Mode buttons.

Right of LCD: Power, REC buttons.

Bottom: Mic, Reset, microSD slot.

Rear camera: Rear camera is little different shape compared to other dual channel dashcams. It's more like a square instead of common flat round design.
The rear mount has a ball joint to rotate followed by a folded design in the middle.
Flat end of mount has two holes, probably for screwing on the car roof or headliner parts.
I'll use a dual side tape or velcro to attach rear cam mount.

Unboxing Video: Play at 2X speed if you want to save time... ;)
Detail rotation of rear camera mount at 3:00 mark.

Review and sample videos to follow once I get enough footage.

rear camera design is quite unusual
yes it's quite unusual design compared to round cylinder ones that are more common.

can't say I understand the thinking behind the bracket they're using either
Here is a screenshot from a video I found that shows how the rear camera is mounted.

G5WA-rear-cam-mount.png

Looks like it's designed to stick on the vehicle's roof liner instead of rear window.
I was expecting a 3M tape or something to suggest how to attach the mount.

Anywho, I'll have sample videos and screenshots soon.
I mounted it little differently.

Too many
Mine is just stuck on the glass mate, seems to work ok and I got the angle I needed - haven't checked the footage yet though.

Folder and files: Same as other Ambarella based cameras except the files are named by date time (much better than sequential numbered file names) and rear camera's clips have SEC at the end of file name.

From the bit rate alone, this is much better than the other dual channel cameras I have.
Even much more expensive one had only 6-7mbps for front and this G5WA has 11mbps front and 7mbps rear, very good assuming other things work out as expected.

Rear camera video is very good , much better than other dual channels I have:

Rear camera is 1080p as well.

Front night screenshots:
Auto exposure control works great. Papago had much blacker video compared to G5WA due to AE.
G5WA with AE makes night videos much brighter, much clear. Nice!

I have same night screenshots from Papago GoSafe 520 here: https://dashcamtalk.com/forum/threa...rella-a7l-chip-ultra-hd-2k.12384/#post-161558
and Papago GoSafe 272 here for comparison: https://dashcamtalk.com/forum/threa...ull-hd-1080p-dashcam.12429/page-2#post-161555

As you can see, G5WA night is much better without any processing.
Papago 520 may have same detail but need to manually up the exposure to match.

To conclude:
G5WA has excellent quality for dual channel camera.
Both front and rear are 1080p and video is great.

There are some issues that I've sent feedback to supplier.
Once they are fixed, this will be great dual channel dashcam and much better than the dual channel I have that cost much more .

due for new speakers there I think ;)
Just the grill covers couldn't handle temperature change from Texas to Colorado.
Speaker works fine.
I'd replace them but I'm selling the car so let the new owner deal with it.
