I don't think it's necessary to have "first hand experience" with them to make an educated guess. If you've been around the block more than once you should recognize all the warning signs of a hustle. Chromed-out shiny "cute" box for cleaning fish ****? The specs (flow rate, etc.), price, and that ridiculous LED screen speak for themselves. Not only would I get a FX5 instead, I would probably take a Fluval405 over the G6. It's like putting lipstick on a pig. Also, reminds me of the story ab out how the US spent millions designing a pen that would write in zero Gs while the Soviets just used a pencil- ie you can get the same job done without all the unnecessary gadgetry and expense.
