Buy cards designed for dash cams and buy them from a reliable retailer. Avoid Sandisk (even their high endurance lines!), Delkin, silicon power. Also keep in mind that MLC is a bragging point. If a card doesn’t advertise MLC, chances are is isn’t. Don’t waste your money on cheap cards because they might fail you when you need them most.

The N2 is a dual lens setup made for viewing the road and passengers at the same time. If you’re looking for the type of camera to view in front of and behind the car you will either need two separate cameras or a unit that has a secondary camera on a wire and hangs from the rear window. This kind of camera is more for taxis or Uber drivers who need to keep an eye on their passengers.

For those interested in a basic 1080p 30 FPS action camera without too many bells and whistles, the F23 action cam takes decent video and has an acceptable build quality. Its best uses would be as a cheap bike DVR for road riders or for someone who will occasionally use their camera and does not want to throw down a lot of cash. While it’s limited by its hardware, it has set my personal standard for video quality in a sub-$60 camera.

This speaker has a respectable audio profile, with a decent mix of low, mids and highs. Due to its size restriction, it does not have much in the way of deep bass, however it makes up for that by boosting the mids. This has a tendency to muffle treble a little bit, but it provides a rich, warm tonal range especially at lower volumes. The awesome build quality combined with the decent sound make it quite a good speaker.

It’s difficult to choose between these two cameras and a lot of it comes down to what you’re looking for in a camera. If you’re looking for something straightforward with decent video quality out of camera and easier operation, buy the M20. If you’re interested in a camera that can be tweaked and customized and has better audio, go for the Git2.

This is my favorite SJCam I’ve tested to date, with excellent daylight recording and a unique form factor. Aside from some needed improvements with the gyro and low light recording, this is a good option for those looking for a budget action camera.
