Pro Great fast documentation lookup
Has a handy sublime plugin. Press CTRL-H and it jumps straight to the docs for that object.

They provide very useful integration with apps that are very fitting with using Dash's features. Once integrated, you can really get the feel for being a must have part of the app its integrating with.
Pro Great utility app to use for snippets

Gives plenty of guides and information on how to generate a docset.

Cons
Con Forced wait time to view docs
If you use the free version you are very often forced to wait 10 seconds to view something you've chosen to look at. If you change apps or lose focus of Dash, it'll start that 10 second timer over again. A real crappy thing to do to your users in order to get them to buy it. Forcing you to waste your time.
Con May keep you out from logging in and accessing your snippets
Con No desktop version
Con Doesn't integrate with IDE
Con Super slow sometimes
You may not be able to login when you need to access your snippets.
