Visi Jet Protein Skimmers

Any one had any experience with this protein skimmer?

They don't have a particularly good reputation, but they might provide some aeration. If you're looking for a skimmer for a 55g, I definitely would suggest avoiding it. For that size tank, I'd use maybe a Coralife skimmer, or, if money was no object, a Deltec. The Remora Pro also gets reasonable reviews, although I didn't like mine.
