I have one and I like it...bought a little 13 watt pc to clip on top of it. The only problem I had was with the pump it comes with. It is a lame little Rio number and was loud, weak, and broke after a few weeks. I replaced it with a better powerhead and it is filled with pods and macro. The slow pump also gave me trouble with cyno...go for it. Oh, and I keep mine on the side of the tank to keep an eye on the action.
