5 stars: Cloud sync between devices is kind of slow, but it syncs with 5 different Android devices anyway. Still using Nexus 6p and few older devices. The built in VPN is worth the cost. If my phone takes a dump, I always have my full account backup to restore from. It's automatic. 2TB of storage anywhere on any computer. Some things don't work when the VPN is on. Must have when using public Wi-Fi
4 stars: I like the Google One service, but with the app had some more features. I'd like to be able to restore from a historical backup, not just the most recent. I am paying for the extra space after all. Also would like to see non-phone/tablet backup ability (i.e. TV boxes).
3 stars: It is very confusing. I have never had any issues with my pictures, videos, files and else until now that I have been warned to download Google 1 or I will not send or receive any emails if I do not do this. I lost almost half of all my pictures when I transfer to this new feature.
2 stars: The backup feature is great, and user friendly. It's easy to find, easy to use. The restore feature? I can't say anything about it because I can't find it. The restore option on the app should be as noticeable as the backup feature. There are many third party apps that are set up this way, but this app is not. This app COULD be great, but again-the restore option is no where to be found...
