Maybe too niche, I don’t know, but Koofr offer some great cloud storage deals such as 1Tb of cloud storage for life! No subscription model. The problem is, their desktop client is way behind everyone else’s in terms of flexibility and functionality. They don’t even have selective sync. They do offer a WebDAV access but that’s not really what the average user wants to get into fiddling with.
After the hideous experiences with the OneDrive client, I can’t say enough good things about Insync!
I will forward this to our product team so we can also monitor other incoming requests regarding Koofr.
