I have the PDF product. I needed to be able to edit/highlight/notate on PDF files and this was was a better priced option. Extremely capable app that does everything I need it to. My only complaint is having to log in to get full features. I'd prefer that they just give you a key in case you need to use it offline.
When I think of the word, "sync", I think of two-way sync. In other words get both locations in sync. This product does NOT do that. I have a local 2TB HD and I tested it by trying to sync one folder. It doesn't sync, it copies. Also, when I seleceted the two filders I wanted to sync, on the cloud side it created a NEW folder with the same name of the folder I wanted to "sync" to. This means it copied EVERYTHING when it didn't have to. It took 3 days. For instance, I had a folder locally called, "guitar". I attempted to "sync" it to a Drop Box folder called, "guitar". Instead of sync'ing, it created a completely new folder within "guitar" called guitar and copied EVERYTHING. That's hardly a sync. Since I could have just done a direct copy and gotten the same results, I will be cancelling my subscription.
