I've been using it for years, never had any problems with it. It does what I need it to, and more - it can host files on the web for you, just as easily as it stores files sync'd across multiple computers. Drag, drop, done. The uses I have for it don't go beyond the free services, but there are extended storage options if need be. I've read about other online file storage options and I just haven't had a reason or urge to switch. Big fan of Dropbox.
