I have been using a CSS for over a year now and allthough not the best skimmer it does what it is supposed to. I tear it down once a week at water change and that seems to keep it level. I will upgrade in the future though because I know this is not the right skimmer to be using long term. If you are looking for something quick and chap this is the right unit, if you want more of a long term skimmer, I would save up for something better.
