Does anyone have a Biotec 5.1 filter? Is it effective, easy to clean?

I'm currently using a Cyprio 1000, but it clogs far too often. I played with
a homemade Flowerpot filter last year, but it leaked like a sieve. I really
think the commercial filters are a rip-off, but the ease of use and
aesthetics are definitely appealing. It pretty much has to go above ground,
as I have VERY little space and few options for hiding. Unless I put it in
the neighbour's yard. I seriously doubt they'd notice in that weed patch.
