I've tried two other fans and they were too noisy (high pitch whine). This one is the most quiet and a decent deal for a reversible fan. The nice thing is that the controls are separate for each fan, so if you only need a little airflow you can have only one fan running. You can also change the direction of the air by rotating the grilles (grating?) - sorry, English is my second language and I'm not sure how to call these:) I find the temperature control pretty useless though.
