Pros
Pro No stitching
Since there's only one lens which captures with a 360x240 degrees field of view, there's no stitching being done.
Pro Suitable for recording sports or other outdoor activities
360Fly is dust-resistant (IP6X certified), water-resistant up to 50 meters, and shock-resistant up to 1.5M. The exterior is also rubberized to make it harder for it to split when handled with wet hands.
This makes it a great device for recording extreme sports or general outdoor recording.
Pro Extremely easy to edit a video or photo once it's captured
After shooting a clip and before sharing it, the app will let you choose which sections of a video to include in the final shared version, add music and even adjust the playback speed of your video or parts of it.
Pro Capable of capturing spherical videos
The 360Fly 4K can be combined with another camera so to shoot completely spherical, immersive videos.
Pro Supports live preview
When the camera is turned on, so is the camera's Wi-Fi and Bluetooth which are used to connect to a mobile phone that has the camera's app installed. Once that's done you can then change the app's settings and have a live view of what the camera is capturing straight from the app.
Pro Reasonably priced
At $120, this camera is much cheaper than similar models.
Pro Waterproof case (30 m)
The camera is water resistant at depths of up to 30 meters due to its waterproof housing.
Pro Substantial battery life
The 1000mAh battery lasts for about two hours while shooting 1440p30. Charging the device then takes two hours.
Cons
Con Poor lighting adjustments
The visibility of images is poor in darker lighting.
Con Issues with recorded audio
Audio captured more than a few feet from the camera sounds rather low and muffled. There's also no way to add an external mic.
Con There's purple fringing around subjects in high-contrast areas
There's some purple fringing when there's a high contrast in the video or photo. This is not very visible on smartphone screens unless you zoom in. However, it's very visible on computer monitors.
Con The view is not spherical
The 360Fly 4K has only one lens which makes it a 360x240 degree camera. Because of this you lose about 120 degrees below the camera.
Con Field of view isn't correct
The camera lens is only 190x360 degrees (instead of the 220x360 claimed) and only 180x360 degrees can be viewed without distortion. This is from an in-depth review of the Amkov_AMK100S by Jan-Markus Rupprecht, which you can find here.
Con 4:3 square format leaves large black areas
Videos are 1920 x 1440 pixels and include large black areas around the circular image. Even below the circular viewing area, there are unused black areas. The effective image area is therefore only about 1.5 megapixels in videos and in photos it is around 4.5 megapixels.
Con Control LEDs on the camera not visible to user
The LEDs have a white-translucent plastic front and appear simply white in daylight, whether they are lit or not. However, the silicone sleeve shades the LEDs, usually allowing for no direct sunlight to fall on it. In addition, the viewing opening is limited only to a few degrees, so you often cannot tell whether the camera is running or not. In this case, the user must rely on the smartphone app.
Con No additional (removable) protective cover over the actual glass lens
Since the lens protrudes from the housing, you should be extremely careful during transport so not to damage the lens.
Con Watch-type remote control not available separately
While the watch remote and camera are available for purchase as a bundle on eBay (their own store), the watch remote can not currently be purchased separately.
