I use it while working in a vendor set up in a tent. This saved me so many times. Had a long charge when it was on the lowest setting and still worked well in Texas heat when I turned it up to a higher setting, it made my contacts dry out a little too much

No bad, it's actually good, the only thing I've noticed is, if it's too humid or it won't blow cold or fresh air instead it will blow warm air, nevertheless this item is pretty good and feels comfortable, depending on your neck highs too.

Used this on my hike up half dome. I used it for 6 hours on the 1-2 speed setting and on the second day it lasted about 2 hours on setting 1 before dying. Charged it for 45 min and it lasted the rest of the 4 hour hike down. I don’t think I would have been about to hike half dome without this. Kept my face and neck cool and didn’t break one sweat on my face.
