Review on O2COOL Rechargeable Necklace Fan Adjustable by Jim Plump

Great idea for a small personal rechargeable fan, but O2COOL needs to redesign it to be quieter. Powerful and generates a nice breeze for its size, but is annoying with occasional rattling and generally too much noise. I don't think it would be noticeable at a loud sporting event, but I'm looking for something quieter. 3 stars because I like all the other features except the noise.
