Nitecore NEF20 Draagbare nekventilator zonder bladen, handsfree, 360 graden luchtcirculatie, borstelloze motor, 4000 mAh batterij, gehard grijs

as someone who is hot blooded this product exceeded my expectations!I live in a subtropical climate and it is difficult to be able to cool off from day to day. this neck set basically cools down your carotid arteries by passing air over them. you can pretty much stay cool wherever you are as long as it doesn't get too hot or too damp outside.great product for the money!

Helping me stay cool when out in Georgia Heat and High Humidity. Blows for hours

Tried these out since Nitecore is a reputable brand. Love these battery life, on the lowest setting I turned them on at 9am and then ran then all the way til I went to bed at 12am. The fans were quiet enough that I didn't have any problems hearing people talking to me, yet strong enough to keep a nice breeze going. Only thing I would note is that it's a tad small for me. I'm about 5'10" 220lbs and a large head so these kinda get in the way when I'm turning my head left and right. Not really a dock against them but I thought they were bigger.

The shape and angle is nice, they rest perfectly on your shoulders. However they really have no air flow on the back of your neck, even after I blocked off the front vents, air literally pours out of the of the back of the fan cover and doesn't channel to the rear. I purchased two of these and both have minimal airflow around the back.
