It came fully charged, but I followed the instructions exactly and charged it 24 hours to be sure it had a full charge. As of now, it still has 87% charge, after getting it Jan 22 (13 days). Thus, I'm not sure it will really have "6 months of battery" like the advertisement claims, but it definitely would last more than a month at this rate. Please note though, that I turn it OFF during the day and only on at night so that might be a factor too. The firmware is up to date so that's what it is. Sorry I can't say more about the battery life, but I don't use it except to get videos like this.
The mounting is also as easy as they claim. It truly is purely magnetic, WITHOUT needing a steel mount behind it to mount. They do provide a separate mounting bracket though with its own steel backing to mount it on a nonmagnetic surface. This is not why I bought this device though, there are better ones if you want to spend the time drilling holes to mount an outdoor cam. But for the convenience of this, it can't be matched.
See the picture of how I have it now. It's not screwed or glued in any way to that (steel) lawn chair. Just put the mounting base (which is a powerful magnet) near anything steel or iron and pop! Right in place and quite secure. You'll actually want to be careful putting it in place it's such a strong magnet you might pinch a finger as it binds to a steel structure. It's been mounted like this for over a week now to get the closer shots that I wanted as in the video. In that time, there's been below freezing temperatures at night, and wind gusts over 20 MPH, and a few hard rainstorms (yes, it's totally weatherproof too!). So that's real too.
The little red light on it lights up when it's recording (it picked me up getting close to take that picture). That's how you know it's on. To be clear, it does NOT record all the time, in a loop in other words. It's motion based. I guess there may be a way to set it up as some kind of streaming cam, but I haven't looked into that.
It rotates very easily in the base, but never loses grip so you can point it at virtually any angle, and it will still be secure.
By default, the night vision comes on automatically, and full color automatically, depending on the light levels, but I think you can change it (in the app) so that the night vision is always on, or always off. I'm not sure though, as I checked now and it's not clear what the different modes there do. Anyway, it's good enough for me.
A few points of clarity for those wondering some other things I was wondering: YES, it has 16 GB of storage space ON the DEVICE. For me it wasn't clear from the advertisement if the storage was somehow cloud based (I didn't understand how they were using the words "local" and "hub", they weren't used correctly in my opinion). But it is indeed local; there is NO need to buy a separate SD card. In fact, there's no way to put an SD card in it; it has no slot for one.
Getting the videos off the device is easy enough. You can download them from the device onto your phone via the app (and a wireless connection between the two obviously). Then you can upload it from your phone to a cloud service of your choice and from there download onto any device with access to the same cloud service. Easy peasy. The charge port is also a USB-C connection, so I imagine it would be possible to connect a USB-C cord to the device directly and download them directly to a computer, but I don't know for certain as I haven't tried that. It's easy enough to get the videos as I wrote. You don't have to download them to your phone to view the videos you can stream them from the device to select the ones you want.
DEFINTELY recommend. I gave 4 stars for the picture quality because it's not true "2K" quality in my opinion but it's pretty high definition I'd say. You can judge for yourself from the video.
