At first it seems annoying and really dims the monitor (10PM here). After about 15 minutes I turned it off and was blinded by the brightness. Its now running again. Wonder if this will make me tired earlier, need to stop this 2am nights.

I like it a lot. I had to adjust the night setting, since all the way to "Halogen" was making everything look orange. I now have it a few steps up and it looks great. Installed it on my desktop and laptop.

It seems really strange at first, but after giving it a few minutes, it's much easier to look at the screen now. I hadn't realized how blinding the "daylight" setting was at night.

I too just tried it. The default night setting is way too orange, but I adjusted it a bit and then got interrupted by an instant message. About 5 minutes later I went to play with the settings again, the daytime setting (my monitor's default) was blinding! I've been running it for 15 minutes now, the orange tint is barely noticeable. I think I really like this, will try it for a few days.
