USB Rechargeable Mini Sports 3-Speed Adjustable Neck Dual

Honestly, for 6 euros, it saves me because I work in a very hot environment and it keeps my head cool.
3 levels of intensity, the battery life is 2 hours and 15 minutes in continuous use at level 1 of intensity. The headset recharges in about 3 hours.
I have a wide neck, it doesn't slip (the back part of the helmet is entirely plastic and not rubber or silicone, it's rigid), but I fear that on people with a very thin neck, it might not be stable. The fans easily orient and maintain their position.
I am very happy with my purchase!

Excellent fan, type C charging connector, three operating modes, fast delivery. Thanks to the seller and my recommendations, this is not the first fan bought from this seller. I haven't checked the operating time, but it is possible to change the battery at any time to a fully charged one and extend the operating time.

It seems a little bigger than I thought. However, the noise is not as loud as expected and the wind is okay. It seems a little bigger than I thought. However, the noise is not as loud as expected and the wind is okay. The packaging is a bit sloppy, but the product is fine.
