It works, but that's the best I can really say about it. You can't make the text any smaller than its default, only bigger; you can't change the text bubble colours or the background/theme, it won't work unless I make it my default SMS app (others will ask but will still work without being default); it doesn't load in a lot of my contacts' profile photos; and the auto/predetermined quick replies are often useless or don't relate to what is actually being said, so it's not very smart.
