I will give it 4 stars because for the money it offers a lot. I use it as a fixed action cam. It has satisfactory wide-angle shooting, not as wide as the GoPro, and definitely worse sound. When it's windy, for example when you're riding a bike, the sound of the wind is deafening. However, your voice sounds pretty good in the videos. The image quality is not bad, but it has a big issue with low light. It is almost exclusively for outdoor daytime shots. The video size is quite large, but with a 32gb card you can easily get 3-4 hours of recording. I don't have an opinion on the battery because I always have it connected to a power bank to record continuously as long as I need it, without worrying about the battery. Since it is the second budget camera I have, usually one battery lasts for 40-45 minutes of recording.
