Cons
Con Closed source
Con No option to authenticate multiple connections at once
When running Viscosity and importing connections, you have to go through and add username and password to each of those connections.
Con Product page plagued by pop-ups
There's a constant stream of full-page, pop-up ads served on the page that obstruct the view.
No ads - just a discount code added as a pop up. I guess is more of a pros that cons
