content: I have owned 2 Targus chill mats and they were the worst pieces of crap I ever bought. They last about 2 months before they stop working. Either they will just completely stop working or the fan blades will start tearing off, and then stop working. After about a week they start making a loud sound like something is caught in the fan blades. Unfortunately, they were the only brand available in my local stores, so I had to settle. I will never trust Targus for any product ever again!!! Sure, they offer a warranty, but to be honest, I'm not going to keep my receipt and warranty information in order to get them to replace the junk they sold to me with another piece of junk that will stop working in the same amount of time and charge me over half of what I paid for the product for shipping.
