Title: Aptly named, the Whisper is quiet by powerful
Review: Not just a surprisingly striking design (for an aquarium air pump, after all), it does exactly as advertised - it provides a steady stream of air and is remarkably quiet compared to every other air pump I've ever used. This model has an easily reversible flow, as well (well, 'easy' compared to other air pumps, which vary from can't to shouldn't), so if you need a little vacuum action (such as for a pick and place pen for SMD components) this will fit the bill nicely.
