I'll throw in my 2 cents as well.
I've had mine for a few months now. Works great.
As mentioned, it is very slim. The unit itself feels well made which is always nice.
As for the remote, it does feel a little plasticy, but hey, it works.
It has (I think 8) preset colour variations. Each are based off white, so they're just different whites depending on how you like it and what you want to highlight.
It also has 4 custom buttons, which you have to figure out how to use, because its not immediately obvious, but its not complicated at all. These are great for setting up night colours so you can watch your plecos, or knifefish (or what ever else nocturnal you have) come out and play.
Something worth mentioning is that its great for a bedroom tank. You can lay in bed and watch your fish without having to get up to turn off the light.
I find the strength of light a little low. Then again I am using the 36-48" model. It will hopefully keep some plants alive, but its by no means BRIGHT.
Another thing worth mentioning is that the extender rods are really long, which means you shouldn't run into any trouble when it comes to reaching the edges of the tank.
