Review on 🌬️ PenKou Hands-Free Bladeless Neck Fan - Portable 360° Cooling, 3 Speeds, Super Quiet & Fast Cooling - USB Rechargeable Personal Fan (Blue) by Theresa Roberts

Device just received, light and quiet. I haven't tried calling on setting 2 or 3 so I'm not sure, but cooling and volume are good on setting 1. The only thing that bothered me a lot was that the Li-ion battery has no memory. Function. Therefore, the user is warned that overcharging or overdischarging will affect the service life. If you have an item that can last anywhere from 3 to 20 hours, chances are it will run out of power. This is a HUGE design omission.
