We love our Fantastic Vents! They have them in different models but they all push and pull a lot of air. We bought the Fantastic Vent covers as well but just keep in mind that a lot of air requires a larger opening on the vent cover, otherwise you'll overheat the fan motors... so whatever vent cover you buy, make sure it has adequate airflow...
