It's really easy to use, it integrates with Github very well so you don't have to worry about syncing files between your computer or mobile device. The software is fast when uploading large projects like games at high resolutions. You can easily upload multiple game assets in one go without having problems of file size limit exceeded errors that other programs might give out sometimes. I'm not sure if there are any downsides but as far as i know this program works perfectly fine for me. If you're looking into using some kind of cloud storage service then definitely check them all out before choosing which ones will suit best for your needs because they do differ from eachother quite significantly. We've been able to sync our project folders across different devices (PCs/Mac) seamlessly through github!
