The 360Fly 4K seems to be a well-built 360 action camera as it is water resistant (rated down to 1ATM, 30 ft), shockproof, and dustproof. It only has a single button, two pin holes for the stereo mics and the charger/USB connection is done through a proprietary magnetized base. So there appear to be no openings to sensitive components. It does provide a 360° left/right rotation around the center point, however it is only 240° up/down. For most shots this is fine as most the action is in front of or above the camera. However, it creates a stretched appearance at the low point and if it doesn’t just stop you from trying to look down you will see a void designed like the camera pattern below. The problem with this is that the higher you take the camera the more you lose in the image. If you sit it lower to get more in the image everything else looks stretched out. The best use I see for this is on the bottom of a drone, as it already removes the drone from the picture and the image you really want to catch is below and not just filled with sky. Though it claims to be 4K, the fullest resolution is 2880x2880 and when uploaded, the highest resolution YouTube gives is 1440p as opposed to 2160p for regular 4K videos. However, the picture quality is pretty good, just not as good as I hoped. Objects close to the camera are clear, but stretched, while objects further away look proportional, just fuzzy. The single button option on the camera limits what you can do by lengths of pressing. Such as 4 second hold can start Bluetooth scan, a longer hold powers it off, and pressing the button starts recording video. Other than that, everything else is managed through the app. The button and the bottom light up depending on the status as well so you can easily see if it is ready or recording. The app is simple to use, provides live video unless recording in 30fps, and allows you to make more advanced settings such as brightness, saturation, and exposure. It also allows you to edit and share the pictures or video from your phone. However, I had issues with the app locking up from time to time, or dropping connection with the camera which seemed to take much longer to get reconnected each time it dropped. Plus the fact that you can’t do anything other than record with the “one button” it became a bit frustrating to have to wait for my phone to connect just to take a picture. Also, on top of that delay, when taking a picture, there is a delay in when it actually captures the image. You can hear the audio on the phone, see the “one button” change colors, but the actual capture is a second after that, as I have a couple of pictures where all I see is my hand grabbing the camera after an intended shot. The app also allows you to follow motion, creating a security camera type feel and allowing you to focus on action automatically. There are planned updates for this functionality according to their website to include other plans for future updates. The computer software is really basic and I was hoping to have more editing capabilities. It actually seemed as if the app had more editing function than the computer program. It basically allowed you to open the files, delete, and share. I like that it is a single lens camera, as there are no stich lines to worry about, but the fisheye lens effect that it gives is very distracting. I like how rugged it is, but there is no storage expansion opportunity or way to replace a battery. I like that it is a standard tripod ¼ 20 thread and includes an action adapter that can be used for nearly any mount for other action cameras. However, for the price I feel there are better options out there. Just since my purchase they have already started an offer for $100 less (Till 8/1). I think with some software and firmware updates to help speed up the camera function, or maybe add a timer like other cameras, it is a decent 360 camera for those that are going to be rough with it. I’d give it 3.5 stars if it were an option and I personally would recommend a different 360 camera to a friend.
