After recently purchasing the 13.3 inch Acer Aspire V3 317 deal off Amazon with HD5100 Iris GPU I noticed throttling when playing games (where the cpu gets so hot it slows down performance). This is a common problem where laptops are unable to dissipate heat effectively.
After purchasing this Mat and plugging the fans in to the USB port, I have no more throttling. The hot air is actually leaving the laptop rather than building up within the unit.
So I am very happy. Especially at this price.
Might be a perfect STOCKING FILLER if you know someone receiving a laptop for xmas.
