The ability to test on any device is great. I am able to do it from work as well as home without having to worry about missing something important. This also makes sure we aren't skipping anything when doing an audit. It can be hard sometimes if you're new using this service because there isn't much help out there and things get lost in translation between customer support and developers which could lead to confusion. Take some time with tutorials provided by redspin to figure everything out before getting started. If they go over how to use certain features then take advantage of this. You will learn quickly once its been set up properly! Testing websites and apps has become easier now that we've used red spin.
