I haven't tried this fan out but I have no doubt it will keep me cool, based on reviews. The flashlight and emergency usb charger are great. My review is mostly based on set-up. Where to open it is confusing the first time; at the edge above the bear's "face", with your nails. The frustrating part was trying to attach the strap. Open the fan, unleash the strap and just holding the string side, loop it through one hole. You need skinny tweezers or a toothpick to loop it through again. Had no problem "sitting up" when blowing but get it started before you bend it back or your hands will probably stop the fan.
