This is one of the greatest items I have ever bought. As one who does not typically write reviews, my Zippi is a life saver. As a woman "of a certain age", finding a comfortable way to stay cool at night has been a bit of a challenge. But with Zippi on my bedside table, it keeps me cool all night and I am sleeping better than I have in a few years. Plus it's cute. And I like it's name. All for $20.!!!!
