I got mine tonight, my initial impression was not so good. The intake design is very much like the one you see with the Prizim series, a U-tube with a little gate valve on it for control. You have to block the air tube to prime it and it's sensitive to water level changes, I really hated that about the Prizim.
Having set it up and messed with it a bit I like it a lot better, it's a well constructed unit and moves quite a bit of water. The gate valve is easy to adjust and once I put the extension tube on it primed really fast. I'm getting a little bit of micro bubbles but it's pretty good for brand new. I also didn't have the oily residue that JSTR describes, just gave it a rinse in some hot water.
Performance remains to be seen but I really think you can't beat this model for the price.
