Works pretty well for me, and pretty stable for a beta, this lockscreen used with timenow = Awesome . But i see is it keeps lockscreen orientation in which it was locked even if we try to unlock it in diffrent orientation, so if i lock in portrait mode and try to unlock it having phone in landscape it will still show a portrait lockscreen but it is not a big issue to me since i always keep my desktop in landscape mode, but since installing it i notice a little slowness in desktop, opening menu and apps, i was using qtlockscreen before but never encountered this so you might want to look into it.
