I agree, never saw one like that before.
In my opinion you cant go wrong with a lifereef or eshopps overflow box. I have been using 1 of each for a few years now. If setup right, theres no chance of a flood.
Are you talking about an internal overflow such as all glass or perfecto? They have holes in the box in different locations to pull water from bottom/middle level of tank. I think the concept is cool but it doesnt really matter.
