I received the 9 pieces I bought. Some fans did not work alone, it was necessary to manually help to rotate the propeller in the first rotations. There is no brand label below each fan. The air that the fan blows is very little, it can be felt in the face, but I believe that it cannot feel very well with the hands. The propeller speed of all fans appears to be low and a small vibration occurs.
Fast Fair price Good quality Well packaged
