Targus Chill Mat model # PA248U Laptop Cooler. I bought this chill mat/cooler for my laptop. It lasted about a year. The cord wears out your USB because of moving around the laptop. Dell laptops get really hot and you need something to cool them with. I really like this cooler because it has 2 fans underneath the laptop where the hot air actually comes from. It keeps the laptop nice and cool. It comes on with my computer and goes off with my computer. The 2 fans are so quiet you wouldn't even notice they were on. After about a year the on and off switch died so I bypassed that and it worked for awhile but eventually I had to replace it. I tried a chill mat iXoft by Thermaltake and that seemed nice, but had its own set of issues. I only could use that for about 3 months until that died. I tried the iConcepts portable cooling station which has a lot of issues. So I went back to the Targus Chill mat and I try to make sure it doesn't move around too much to wear the USB plug out. I recommend this product for laptop users.
