I like how easy it was to set up, no problems with that! It's just great for managing bookmarks in different browsers without having multiple accounts or apps installed across devices (which would be extremely tedious otherwise).
The only downside here really has nothing do directly w/ this app - but rather what you're looking at using your computer when working online via internet explorer etc... which isn't very fun sometimes. Managing all of my links within one place so they are easily accessible from any device i'm logged into online as well as offline.
