I am giving 3 stars mainly because the flow is not adjustable. Anyone who uses a bio-pellet reactor knows that pellets can't go faster than 1000mph lol. They need to be set in a slow case just to keep them moving at all times. Too fast and they're basically useless, I'll give them a week to play around with them and try to limit the flow if not. get a star. It's very expensive for what you get. Update: sorry, sent back
