Lacks documentation and you will have to figure out the menu system yourself. The latter is not all that user friendly (user hostile?). Hang in there, the camera did format my 128GB memory card once I found the setting. On line help was not very helpful. Took several days to figure that out. The accessory mounts are likewise a bit hard to figure out.Despite all that it is a very nice unit, has amazing capabilities and is worth the price and initial frustration.

Plenty of memory and easy to use. I highly recommend this.

Haven't had a single problem with this memory stick.

I am not an expert on this but very impressed so far for the price. I actually bought it because my neighbor threatened us and I had no way to get a wifi or plug in camera on my animals. The instructions were a little confusing and the test part seemed so simple I was afraid it was too good to be true. I put it up about 3 weeks ago and just today took it down to review the footage. I couldn't figure out how to do it on the device so I removed the memory card. First issue, it says to put it 3 or 4 feet off the ground. That's probably perfect for an actual trail cam, but for my purposes I put it about 5ft high on a fence post and it went off over and over and over for 2 days because of my ducks and goats and then it was full and stopped recording. Next time I will mount it much higher for my specific purposes so my own animals DON'T set it off, I also got a bigger memory card. Second, the video quality is fantastic. I could not believe the clips I was watching were from a fairly cheap trail cam. Even the area in the background that was wooded that I wanted to cover (the property line) was pretty darn clear. My advice for buyers is just to put it up, do the test in the instructions, and then within a day or less pull the memory card and watch the clips to see if you need to adjust anything. I didn't do that so didn't know it was full and missed a dangerous incident, so just make sure you double check it after placement to be sure it's good to go.

This is my first experience with an action cam and I like it. It came with more accessories than I knew what to do with. The video quality was good and it has a 4k option but it uses a ton of memory. The battery life is good and I love that it came with two batteries! My only issue is I originally bought the wrong SD card. It supports up to 64MB and I bought a 128. All-in-all I feel like its a great value for the money!

Using it for a security cam. Tons of memory space and no pixelation

It holds a lot of memory and is easy to upload on an Apple device.

For increasing the Playstation 4 memory. Works just like it suppose to.
