I like that it's easy to use, simple, and free! There are no ads or popups so you don't have to worry about getting distracted. There is nothing I dislike really. It works well, and is very user friendly. I'm sure there is something I am missing, but I haven't found anything yet. I hope they make more improvements in the future.
