Do yourself a favor and buy a different camera
For those of you that don’t like reading, here’s the short version. Don’t buy the Drift Ghost 4K. There are much better cameras out there. Disclaimer: I am not a motovlogger. I bought this camera as added insurance.
-Specifically designed for helmets. It's not super polished but it works.
-Battery life is OK. Option for swapping/upgrading battery is a plus.
-Buttons are easy to press with gloves on.
-Comes with BT remote. Again, not a motovlogger. Also, I wear gauntlet gloves so that’s a no-go. YMMV.
-This camera looks OK attached to a helmet. Obviously, having no camera looks better tho.
-NOT waterproof/resistant. You can look up the exact spec but the housing is poorly made/assembled and there are some spots where you can actually see inside. It’s clear from their promotional material that water resistance wasn’t high on their list. Sure, it has rubber port covers and a gasket where the secondary battery connects. However, if water gets inside the camera and causes a short, none of those things matter. Most action cameras now are water resistant to several meters so this is a serious flaw IMO.
-Presentation/packaging/quality. My first impression was that it “looks like it came right off the shipping container” (aka Alibaba special). Build quality is cheap to put it mildly.
-USB Mini-B (5-pin) port. Remember the Motorola RAZR (the flip-phone not the Droid)? That’s right kids, Drift has opted for some retro-nostalgia when it comes to charging/data transfer. Seriously, WTF!?!?
-You have to disable cellular data to connect the camera to your phone (via WiFi).
-Video quality is… garbage for lack of a more scientific term There’s a lot of noise. The camera does. not. want. to. focus. Oversaturation is a real problem even with “normal” settings turned on (no filters). Think Alice in Wonderland (the LSD version with Johnny Depp). Visually, there’s not much difference in the raw footage between 1080p, 2.7K, and 4K. I actually had to look at the metadata/bitrate to figure out what I had recorded in. I know some reviewers have praised the video quality but I can only speculate they are coming from VHS or something. Even smartphones take better video now. Geez...
-”Error” forces the camera to shut off after 10-15 seconds of recording (I saw this mentioned in another review too). The problem seems to be mostly fixed by firmware updates as it doesn’t happen as often now. I use a brand new SanDisk Extreme 128GB MicroSDXC card (U3, V30, A1 speed ratings). I’ve tested the card outside the camera. This is 100% on Drift’s end. It sucks because I’ll start recording and pull away but I won’t know if there’s a problem until I go to look for the footage later. The overheating issue (see below) only exacerbates this problem since SD cards (read: all solid state storage) don’t like high temperatures.
-It overheats. Drift updated their site a few weeks after I purchased mine (I know because I had done a search previously and there was no mention of overheating). LiPo/Lithium-Ion cells are very temperature dependent. They can suffer thermal runaway, if overheated, leading to “vent with flame”. The battery label for the Ghost 4K specifies a MAX operating temperature of 60C/140F. I tested the camera several times after I bought it, but only for a few minutes at a time. It did heat up substantially after 10 minutes, which I thought was odd. During a road trip, I went to unclip it from the mount after 45-60mins of recording. It was so hot that I actually dropped it. I’m guessing the thermal envelope was approx. 140-150F. I was really pissed off. I remember pulling over into a Wal-Mart parking lot to text a friend who was thinking about buying one. He suggested that they were only meant for helmet use. However, Drift clearly intended for the camera to be used in closed vehicles since there are several features labeled “dash-cam.” I wouldn’t recommend using it inside your car, especially if you have kids or loved-ones or pets. Cooling IS better on my motorcycle helmet at high speed but sitting in traffic or using as a dash cam and I worry about becoming the human torch.
Conclusion: I was really struggling to think of any other pros. There are just a lot of better options out there in the same price range. You have GoPro, Mohoc, Contour, Garmin, etc., all producing excellent action cameras. Overheating aside, the Ghost 4K WOULD have been a good camera, 3-4 years ago. Right now there are much better cameras, with more features, that take better footage, for approx. the same price. I really hate the GoPro mounts but I’m already looking at the Hero5 Session (or the new Hero 6) as a replacement.
