Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Be hesitant...many faulty products

This CHI was the third that I bought inside of a month. I bought and returned two at a store by my house, and both were faulty. I figured it was the store and bought one off Amazon. This one worked...for less than a week. I can't consider it a coincidence any more. This item is not reliable enough for how expensive it is!
