I'm looking to pickup this guy and was curious about the negative experiences anyone has had With it. The site selling it has tons of food reviews but I'd like to hear of any potential downfalls before I drop 70-80 bucks on a rba. I'd like a bottom fed style setup mostly I know using my vivi Nova ATM is fine but not perfect . And the only other one that caught my eye was the "Pali v4" although it has no feedback from what I could see
