I received this product as an early birthday present and absolutely love this product! The low setting is quiet. The mid setting is not too loud and the higher setting offers more sound but I can still hear over clients in my office. My co-workers are interested in purchasing the same one and have commented on the round, sleek design and the fact it doesn’t take up much space.
                    I feel safer working in my office when this product is on as the HVAC system in our office is somewhat dysfunctional. When I have this device on, I cough less and don’t have a headache.
