I don’t know what the tefal engineers were guided by when they came up with a 180-degree airflow))) if you only place the vent in the middle of a large company or in a dorm room where there are beds along each wall. IMHO, it would be enough to rotate 90 degrees to blow the required area from a distance of 2-4 m. I would like even more calm and quiet airflow at first speed (for example, for night mode) I bought Tefal as an alternative to the Polaris vent in the classic "blade" design. Despite approximately the same price, Tefal wins in design, ergonomics, and compactness. In general, a good device, not without minor flaws, probably the device could have been made better.
