The great qualities of RebelMouse include the ability to quickly and easily post and repost content. Additionally, embedding the widget onto a 3rd party site (e.g. Wordpress) was fairly quick and seamless. The client was extremely happy with how fast and easy it is to share and create content in this system.
The out-of-the-box customizations are somewhat limited, and when our team attempted to make CSS overrides, it ended up being very tedious and ultimately impossible to customize at the level the client needed.
As long as you're willing to work within the sandbox (e.g. built-in templates, styles, etc), it can be a great solution for easy content curation across the web.
Our client needed a solution that would allow them to (specifically their CEO) to share industry-relevant articles across the web and social platforms very easily (from his phone). RebelMouse ended up being a great fit for this need!
While we were not able to stylize and customize the look and feel of this product adequately, we were able to create and manage multiple feeds/categories through the dashboard. And the support team was quite responsive, but sometimes it was hard to tell if the support rep was not educated on the product or if the product did not measure up to the requirements we had for the project.
