Bests & Worsts Reviews from Amazon

I'm a postal worker in California, and the days are quite hot, I tried this item out I am not impressed with it.. I would have to say it's not designed for continuous use in hot environments. I had it fully charged and it lasted about 2 hours on the highest fan speed. It did get cool but the cooling kept shutting off after some time. The device would emit 1 beep. I will be returning it as its not worth $160. Update im still pondering returning it, but I used it on medium power and it lasted longer. And cooled more efficiently. Stand by for further updates. Update 2 I have decided to keep it, it works great on medium power and lasts about 4 hrs. It does bring relief when it's hot. But to be fair it doesn't do well at Temps 104 and up.
