Bounce.Page was appealing on paper, so I get the Tier2. After few hours, I can say that it's very ... basic. Not a lot of customization, some components are really limited (ex: tables, they are 2-columns, you can't add others).
The editor is not so bad, but not so good. When you add lot of components, it's a mess, difficult to reorder your components, they're all uncollapsed so you get a loooong editor page in height.

It will probably be better in some months, but right now, there are other similar equivalent apps, much better. My best one is Kites, there on AppSumo, much more powerful and in terms of customization, the sky is the limit.
