The fact that I was able to get my portfolio together in just one day! It really helped me understand how everything works, what you need as an artist/model etc..
There is nothing bad about this service at all - it's great for people who are new or have never used any other services like these before (like myself). If there were more options of different types available then i would say go with those instead because they're better than gopro anyway so why not? You can easily upload videos from anywhere using their app which makes life easier when traveling around Europe doing photo shoots / modelling jobs; however sometimes some locations don't allow cameras inside them but still require video footage uploaded online afterwards via Go-Pro apps such as Vimeo Pro & YouTube Studio App.
