I have one at home by the bed to circulate air at night. I have another one at the office to keep air circulating in my cubicle. It is quiet enough to not disturb my peers, yet powerful enough to provide constant air circulation and safe with the fabric blades. The Zippi is so quiet, people entering my cubicle don't even know it's there until they feel the breeze...and then they are entertained by is power, color and safety fabric blades. After 3 plus years of constant use, who knew my office fan would continue to startle unsuspecting visitors! ;o)
