I got this hoping I wouldn't need to end up getting a GoPro, but alas several problems with this mean I'll probably be returning it.First the good. The quality is pretty good. The fact that they let you specify the bit-rate (in terms of low, medium, and high) is a nice feature. In general I think the picture quality works well.But there are several things that are super problematic. One is that the Wifi mode, which lets you control the camera with your phone, can only be turned on when OUTSIDE the case and not attached to something. So if you get it inside the case and attached to something (like a head or chest piece, etc.) and have forgotten to turn on the Wifi, you have to unmount everything and take the camera out to turn it on. It's mind-blowing that this is the case. If the camera turns off because you're taking time to get everything mounted again, you have to re-enable Wifi again.The app that lets you control the camera doesn't give you access to all the features that are available to the camera directly, and some of them are very basic, like the FOV (wide, medium, etc.). So again, if you want to gain access to those features, you have to unmount it from an accessory, take it out of the case, set that, and then get it back in and set up again. Again, it's just mind-blowing that they haven't included all the features in the phone app.These glitches make it very painful to work with in a real-world way when trying to use attachments.Edit: I was using the water proof case that comes with the unit. I've now got the regular case installed and that does make it easier to enable various options, including the Wifi mode. But it would still be much more useful if Wifi could be enabled without having to get access to the screen. And yes, the camera app definitely needs to have all the functions, not just a subset.
