They have a free level, so you can just sign up and try it out.
I would say the main thing that I noticed different from other services is that the end to end encryption means you can't stream videos. So when you're browsing your family videos, it has to download the whole video before it will play. This will leave you waiting a few seconds or more compared to big tech non-encrypted video playing which will stream so will start faster.
Other than that, they seem good-intentioned, they have been around a while, their product seems high quality, and if I wasn't self hosting I'd probably use them.
Though I do have questions about their other product, a cloud-synced 2FA. I might be missing something but if I can log in to their website to see my 2FA codes then it doesn't seem very 2FA.
