My personal experience with Amazon has been great its not all sunshine and rainbows but hey not everything in life is. Im a prime member so that just makes everything better free 2 day shipping with already good prices on some items sign me up and theres a vast variety of sellers its awesome. I personally use it all the time its great I highly recommend it to anyone.
I would compare it to something similar like a diffuser. This is actually good as it is just enough of a mist that it cools you without soaking your face. The combination of the fan and this fine mist will lower the temperature enough that it will blow cooler air. You dont have to be a Science Wiz to understand that concept.
