I've been using this for about a year and a half now... Protip: the fast transition speed is a little jarring, I found. If you really want to "set it and forget it"... set the transition speed to slow and you won't even notice that it's changing over time. Also, make sure that the color temperature it goes down to is correct. Otherwise you will have a noticeable color cast at night. I have mine set for fluorescent lighting since that's what's around my desk.

The goal here is to essentially forget that flux is running yet reap all of the benefits of it.
