Review on 👕 Portable Neck Fan 2021 – Ninetails Rechargeable Personal Fan with 6000mAh Battery, 360° Lightweight Wearable Design, Low Noise 3 Speed Hands-Free Fan for Indoor & Outdoor Use by Megan Spencer

Unfortunately bought two. I rarely give negative reviews, but in this case I think it's justified. Have both fully charged. BOTH lasted no more than 20 minutes. The battery life is NOT between 4 and 20 hours as described. Sits slightly around the back of the next one and falls off when you walk with it unless you tuck it under a t-shirt, which I did when mowing the lawn. Which took about 40 minutes and took about that long. Relatively light and easy to use. Silicone allows for better rotation of the vents but as said is a bit bulky around the neck, short battery life and sadly not happy with this purchase.
