The service offers an excellent 15 GB free program for its users. If you wish to get more, you’ll have to upgrade. Their plans are a bit different since they come with a bandwidth limit. Apart from that, they have a very modern and responsive client. Download and upload speeds are slow at peak hours, and the sync&sharing feature is decent with some negative aspects. They also offer browser extensions, direct FTP access, secure chat and a very well made mobile app for iOS, Android, BlackBerry and Windows Phone. Online support is limited to e-mails and poor FAQ base. Their security is where it needs to be with client-side encryption. Overall a very viable pick, but there are better options out there.
