My fan will not run on the high speed when plugged into the usb port, only when it uses battery power. It always shuts off when I try to use the high setting. Other than that, it is great.
I've had the fan for a month now. I use it 3 to 4 times a week for golf and its greatly appreciated in south Florida. First it has a much better clamp than the same fan without the misting feature. I own one of those also. It stays attached no matter how big a bump you hit. The fan portion is plenty strong and lasts for a full round on high speed. The misting feature is well worth the extra few $. It has two functions, constant mist and an intermittent mist. The intermittent mist will last for the entire round while the intermittent will need to be refilled for the back 9. Very satisfied with this fan.
