I like that it is easy, intuitively use! It was perfect when we needed something quick but also very useful in case of longer workflows or more complex cases (ease-ofuse). The price has been good as well; considering how much time you spend using this tool there's no reason not buy at least one license right now if nothing else came up yet. We are solving two main problems here - being able manage all our tasks/to do lists together easily while having access from anywhere thanks to mobile clients etc., plus be sure any file sent by email can still later edit after received via other means such sharing through cloud storage services etc.).
