I am returning this because when compared with other which cost me 22.00 this one has less battery life. Also the structure is not the same. However, it makes the job if you can not pay more.This can was economical, light, adjustable, compact and the airflow was perfect... one time. I may have been able to return the item but I purchased it over 30 days ago. Too bad.It does a goo job of moving air, but it is a bit cumbersome around the neck. Not bad I guess for some outdoor activities, but I would be afraid of it falling off if I moved around too much.Works well, very adjustable which is nice. Doesn't have a very large battery so I'll need to be recharged oftenthis is easy to use and charge, I would be careful when you drop it, it does come apart and you can snap it back together and it still works fine.Es frío al principio pero después de 30 minutos no se siente el aireI charged it until it was green. Unplugged it. Tried it out. Turned it off. When I needed to use it the next day it didn't turn on even when plugged in. It does blow a lot of nice cool air right on your face and is easily adjustable light weight doesn't make your neck sweat. I wouldn't buy it again and will likely return it. Very disappointing.Not as advertised. Quite annoying to adjust to the right position.
