I never used it but it's an odyssea product and usually anything from eBay with the odyssea label on it is usually cheaply made and not a very good design structure.... I would be cautious on buying it. If you are in the market for one as I am I would look into LifeReef.com They usually have the bst Overflow Structer made and maybe a CPR Overflow. Which are good to use as well... I heard a lot of good things about both.... But that's JMO...
Tank,
If you are looking for one also then check out the Eshopps on ebay.
That is what I currently have and it has never failed, always restarted on its own and easy to adjust. I'm just looking to upgrade and didnt want to pay the price for the 1200.
