I've really liked it so far! I like the visual customizations  I've never seen an app that lets you customize even the app icon. That being said  it has crashed quite a few times. It also does have a few behaviors that aren't like normal apps  such as double tapping on a message from the lock screen doesn't bring you straight to the message. It just brings you to where you were in the app  which may have been a different message thread. So overall I like it  but the crashing has been just enough to drive me to find a different app.
