The most amazing thing about it is its flexibility, i mean you can do anything with this tool in terms of automation! It's easy to get started but requires some time for getting used too well (and learning all).
I would suggest going through their documentation first so that when something goes wrong or doesn't work as expected - then there will be someone who knows how things are supposed ot go around here :) We have been using atomists services since last 1 year now & we love everything from UI testing till deployment part which has helped us automate our entire workflow process very efficiently without any issues at hand!
