Review on 🌀 Portable Neck Fan, Hands-Free Personal Rechargeable Fan - USB Mini Wearable Sports Battery Powered Face Fans, Suitable For Office, Outdoor, Travel (Black/Red) by Richard Gaines

To my surprise, I bought 3 pairs of these. You are terrible. The battery only lasted about 2 hours after being charged all night. On the "high" setting, you can use a piece of paper as a fan to get more airflow than here. The fan curve on the blades is very poor and inefficient. They look good and the price was good. But heed the warning. After all, they won't do you any good. Only pay for really good brands. They even have a guarantee. If for some reason you've gotten this far. To activate the 0 instructions unchanged. Press and hold the button for 3 seconds to turn on the low speed. Press three times to switch between speeds. Press and hold the button for 5 seconds again to turn it off.
