Pros: This camera takes pretty good video, I've only tested it in my fish tank so far, which is well lit, but I've been happy with the video quality. So far the battery has lasted a long time, I forgot it on for a few hours and it was still running. The design seems pretty good, I read one review about water getting to the camera, but I have not had that problem at all. I like that it comes with extra gaskets so that if the original ones start to go out, you have a spare set.
Cons: I wish there was an app or something to view the video and control the camera while its on from my phone. You have to be very patient and connect it to a computer later to see the video. You have to unscrew the back of the camera to turn it on or start recording video, because its all sealed up there are no buttons or places for water to enter, and it seals very tight so it can be difficult to open with wet hands.
Overall, I like the camera and it has exceeded my expectations for a underwater camera at this price point. I will try to upload one of my test videos soon to show the quality of the video.
