This handy little clip-on table fan, battery operated, 4 speeds and 360 degrees is perfect for my desk and also easily attaches to the frame of a large crib for when they come to a sleepover that later will be of great help as our historic home does not have air conditioning. With a battery, it's actually quite amazing that it can be used without limits. It doesn't matter how it is attached when rotated 360 degrees. It's very flexible. The amount of air this little fan can release is pretty amazing. It will be of great help wherever we use it during the hot summer months we are about to enter. So glad to have it. I definitely recommend this fan and will probably buy another one in the future. Good product!
