Review on JDSUMS USB Mini Fan, Hands-free Neck Fan Portable 5 Inch Hanging Fan, Rechargeable 🌬️ Battery Powered with 3-Level Speed, Necklace Fan Multi-Functional for Travel, Sports, Office and Outdoor (Pink) by Kenny Hrdlicka

The fan performs its functions but has a major design flaw. The power button is on the bottom, so you can easily accidentally press it and turn it on or off. I bought it mainly to travel, especially to fly. This means it must be removed if it passes through the TSA or if not in use. It is very easy to press the button and turn it on. Many times I would open my bag to get it out and find that it worked or that the battery was dead because it was in the bag. I just bought another one. I hope he doesn't have the same bug.
