I use this fan in my bedroom. I currently own 3 identical ones. This fan does not move and is only used on a warm night. I was asleep and awoked by a loud noise that was quit scary. The band holding the 2 spherical cages that enclose the fan blade, split and went flying across the room. The customer service reps, Kathy and Aramis were of no use! They couldnt care about the potential danger!!! The supervisor as well was uninterested and telling me that I could buy a part for $40 when the fan costs $65. I am prepared to go thru social media and let potential customers know how Rowenta does nothing for their customers when confronted with a dangerous product. I would like a replacement fan at no cost.
