Review on ⚡ MoKo Portable Neck Fan - Hands-Free USB Mini Fan with Rechargeable Battery, LED Light, 3 Speeds for Sports, Office, Outdoor Travel - Black by Shannon Sims

I bought this because I wear glasses and they fog up during a mask crisis. I use anti-fog drops on my lenses and this fan and it's a game changer. I can actually look and feel cooler as the masks also make you feel a lot warmer. My biggest complaints are that the battery doesn't last very long, even in low light, and the battery heats up during use, making it hot on the back of my neck.
