I like how easy it was to set up tests, as well as run them in parallel or sequentially using different configurations of browsers/devices. It's not free though but you can get started for $5 per month which isn't bad at all considering this tool has helped us save so much time! We were able to do things we couldn’t have done before such as test features across multiple devices (mobile vs desktop) without having to manually download each version separately every single day. Also being able to use our own cloud services instead of relying solely on their hosted service. The reports are also very helpful when looking back over past results. There really aren't any downsides about running these types of tests through Boozang other than maybe they could provide more options regarding what type of device configuration would be optimal depending upon your needs.
