GoPro Hero 7 Black Review

Has 12 voice commands, such as, start recording, stop recording, take a photo and Turn Off to name a few.

It's about the size of a 7th gen iPod nano, so it doesn't require you to carry around a backpack or a bag, because it can easily fit in your pocket.

It’s a great action camera because it has class-leading video quality, amazing stabilization, plethora of mounts, and it can survive water, getting dropped and all kinds of weather.
The Hero 7 Black outclasses both the Silver and the White by a significant margin. Being able to record 4K60 over 1080p60, retaining quality in low-light situations, on top of that. Thanks to its HyperSmooth stabilization technology the video filmed on it is smooth. This one without a mount/stabilizer is comparable to a Hero 6 black that's with a pole mount stabilizer.
You can mount it to basically anything that can get the mount attached to it. With already having a number of different ones, there's a mount for your bike, for example. Then there's the 3-way grip and so on.
It is water-resistant down to a depth of 10m (~33ft), so naturally, rain will not hurt it either.

It has a livestream option that lets you stream directly to facebook. This can be really useful, especially to walk and talk style vloggers.
