i think a lot of the comments said it all, overpriced shiny gimmik, flow drop-off meter? i can see when the flow has dropped, w/c monitor? i do it weekly. its very stylish yes, but for the most its going to spend its life in a cupboard and even if left on show will soon be covered in crud, unless your sad enough to polish your filter casing. as mentioned above, for the money i'd expect a UV and heater at least. Best news is that with a new arrival all older models will slowly drop in price so FX5's should be affordable in a couple of years, though to be fair i'd still like to move over to Eheims.
