More than I can review. ;)
Thank you @GearBest for providing review sample.
It is available @ Gearbest for $72.99: http://www.gearbest.com/action-cameras/pp_234333.html*********************************

*********************************
Conclusion: will be added after tests
*********************************
Description:
This camera is advertised to use GoPro3 accessories so the body size is same.
It uses NT96655 chip and 12M Sony CMOS sensor.
It has built in Wi-Fi that's great for setting the FOV angle as well as for live view monitoring.
You have to download Firefly app using the bar code in the product manual to use the Wi-Fi feature.
[Note: I downloaded Firefly app from google play store and it didn't work, couldn't connect to camera.
So download using the bar code in the product manual. It takes 1/2 hour to download due to slow host connection but works.]


There are few things that are interesting features in this camera.
Adopting back illuminated Sony CMOS sensor.
FOV can be changed to Large, Medium, Small via menu settings.
.65” OLED screen in the front.
Time-lapse video at .5 or 3 second intervals. (This can create time lapse videos so no need to join time laps pictures).
1600mAh battery.
For more info, please click the link: http://www.gearbest.com/action-cameras/pp_234333.html*********************************
Quick unboxing video:

*********************************
Package contents:
The product box is very small and camera is packed nicely in foam inserts.
It comes with minimal accessories.

Besides camera with lens cap, it only has product manual, mini USB and AV out cables.

However, since it's same size as GoPro 3, there are many accessories available to buy depending upon its use.

Buttons and features:


The small screen is very handy.
Camera has up/down buttons on the side that cycle through settings.
Pressing Up button for few seconds turns Wi-Fi.




*********************************
Front: .65" OLED screen, Power button and lens with lens cap.
Firefly 5S is front left. Others are SJ7000, Ausdom A261 and Git1.

Side-by-side with Git1 that is exactly same size except the lens housing that's little longer on Git1.

*********************************
I never had GoPro so this is my first action camera with screen on the front face.
The only trouble with having screen on the front is that I’m using it as a dashcam and it’s really difficult to operate/check the camera as it’s facing the other side.
Blue lights on power and shutter buttons flash when recording so that helps to at least know it’s doing something.

Video samples to follow...

Firefly Wi-Fi app:
As mentioned above, I downloaded Firefly app from google play store and it didn't work.
Phone connected to Wi-Fi but the app couldn't connect to camera.
So I downloaded the app using the bar code in the product manual. It takes 1/2 hour to download due to slow host connection but works.
It could be a different version that's on the google play store.

Turn the Wi-Fi on either by pressing up button for 3 seconds or by going to the menu.
The camera screen will display Wi-Fi icon and password.
Open Firefly app and it should display live camera view.

This is the one I downloaded from app store and didn't connect.
It's just to show what the app logo looks like.

Once connected, the app can start/stop recording, view/download files along with various other settings.

The wifi got disconnected several times when I tested it because my phone was trying to get on the internet with this wifi.
I think there is a setting in the phone to disable checking internet connection so need to do that.

Firefly 5S Folders and Files:
Root folder has DV folder and it has a sub-folder named MOVIE that has all the video files.
File names are named with date and time so very easy to find particular file.
5 minute file is around 440mb in size or 450mb if calculating at 1k byte instead of 1024.

Firefly 5S Daytime screenshots:
Video is of decent quality but underexposed.
There is no out of focus area in FOV which is a good thing but video quality could be better with higher video VBR instead of only 11.1 mbps.
Also, it underexposes too much in mixed light conditions like evening drive with sunlight that came out very dark.
I'll test with increased exposure sometimes.
Firefly 5S doesn't have option to flip the video upside down so I had to do that in youtube after uploading.
I think all action cams should have option to rotate video upside down.
Audio is very good.

Few daytime screenshots @ 1920x1080p:
Notice the time stamp in upper left corner. Normally it's on the bottom right corner if it had flip option.
Also sorry about the black left side, it's partially blocked by another dashcam and I had hard time connecting to Wi-Fi to adjust FOV.

Little bit too dark footage as shown in the screenshots below:

The above image should be this bright taken by Ausdom A261:

It's much brighter outside than what the video has:

did you travel to europe just for this review? i mean... a traffic circle? :p
There are two on my way but enough of them already.
Both roundabouts are right next to each other.

That picture is very dark as Firefly underexposes at it's default 0 position.

Here's how it actually looked at the time of video with Ausdom A261:

Firefly 5S Daytime videos:
Video is in line with G1Wx quality but little underexposed.
Audio is very good.
It doesn't have image rotation setting so the date time stamp is upside down.
I set it to record on power and it won't stop afterwards even with repeated pressing of OK/Shutter button so had to turn power off.
Will test more on that but was little frustrating. (Edit: Found this issue was due to the frame I'm using. The frame was pressing on buttons on the side and it won't respond to anything else. Need to find open frame that doesn't clamp on all sides.)

1. Beautiful Fall Morning and driving alongside mountains:

2. Driving alongside mountains:

3. Sunshine to lighted underground parking garage:

4. Afternoon rush hour traffic:
@ 2:45, one dumb/smart driver is stopped on right only lane to merge back.
I honked and he flipped me even though he was the guilty party.
Audio muted at the end but registrator viewer added some static noise.

5. Afternoon against Sun briefly followed by nice sunshine and fall colors (very dark video compared to what really it is):

Actual brightness should be like this VIDEO from Ausdom A261.

If you'd like to compare these videos against other dashcams, click below:
LUKAS LK-9370 and more LUKAS LK-9370
AUSDOM A261

Will test at night soon...

My videos :)

Just confirms Firefly underexposes too much.
And bad thing is there is no EV setting to change.

Firefly 5S night screenshots with high/low beam test:
It captures night objects pretty good where there is headlights or traffic lights.
Roads look pretty natural without too much grain but it's very underexposed so everything looks very dark.
To make it worse, there is no EV setting to increase exposure.
In other words, night video quality is not as good as expected from the hardware specs.

Compare the above night screenshots with Git1 here: https://dashcamtalk.com/forum/threads/review-gitup-git1-pro-wi-fi-waterproof-1080p-action-camera.14334/#post-189260
There are few screenshots at the exact same spots.
No comparison, Git1 is much much better.
Git1 captures a lot more light, everything is brighter.
Git1 has sharp footage compared to Firefly's slightly fuzzy footage, specially if you check the street lights flowering up with a fuzzy halo around them.

Firefly 5S night videos with high/low beam test:
I switched headlights to high/low back and forth in residential areas to see the difference.
From residential area to traffic intersections.
Audio replaced.


Night videos have good color but footage is very dark and there is no option to adjust EV.
