I have been using my laptop computer so much lately that I began to worry about problems with it heating up. My husband picked up a Targus Chill Mat for me the last time he was at Office Depot, and I have been using it ever since.
This mat has been effective in keeping my laptop from getting too warm with prolonged use. It plugs into my laptop through the USB port, and I sit it on my lap and work with it that way. The mat has two fans and is compatible with both PCs and Mac computers.
I did think it was rather expensive at $35.00 because the design is pretty simple. But the mat has been helping to keep my laptop from heating up, and my lap never gets warm when I use it. So I must say that it has been effective so far and has proven to be worth the price paid for it. Of course, time will tell how well this chill mat holds up, but so far I have no complaints with it. The USB cable fits conveniently into the back of the mat, and its compact size allows me to put it into my laptop case along with my computer.
I would never use my laptop without the chill mat, now that I see how well it works. In fact, the reason I decided on a chill mat was through some SR reviews I read about how good they are.
