Good - not perfect.
I like it, and in a weird way, it has lead to me using FaceBook less, because rather than logging in and browsing and wasting time, I just click on notifications. I thin its saved me quite a bit of time.
The one thing Id like to see added is support for animated gifs. As of right now they dont show, and while it seems weird to knock an entire star off the rating for this, I find many of the gifs pretty amusing. Once gif support arrives, Ill adjust my rating accordingly.
Otherwise I love it, its great for messaging and going onto FB less. Solid tool, the best Ive seen and definitely worth the price.
