I use Cerberus to do non-regression testing, along with testing of new functionalities. After a change or correction to an application it is great to be able to trigger a testing campaign in Cerberus that will make use of all the tests defined in the past for that application (not only by me, but also by other team members) to test it for non-regression, in multiple browsers and variations of the application (for example, PT and UK variation). I don't give it a 5-star rating because although it is easy to use, it has a learning curve that could be smaller - something to be taken care in future versions.
User friendly and allows you to use tests previously saved in the library
Ease of use, scalable, enabling real continuous testing loop
