Review on 🌬️ Stay Cool Anywhere: YIWEI Portable Neck Fan - Hands-Free, Rechargeable, and 360° Degree Rotation for Office, Travel, Sports, and Outdoors by Carol Long

Fan design is great. 3 speeds. Easy to use, not only can it be worn around the neck, but also used as a small desk fan. However, a fan stopped working after a few weeks. I tried several things but I couldn't get it to work. I emailed the company and received a full refund within 2 days. So if you're in doubt about buying them, I think there's some confidence that if you're not satisfied, the company will do the right thing. I used a return on another pair.
