Title: Noisy
Review: I bought this small one and a bigger one from Tetra. This small one is noisy and vibrating (no load), not any quieter than the one I was using 10 years ago. The bigger one however is much quieter, but it's definitely no whispering either. Anyway, I don't intend to use it inside the house.
