I am pleased with this support ventilated for several reasons: -l'air expelled headed over almost the entire surface of the support, unlike some media that simply did cool down a part of the cell, where your air intake is not necessarily located. -this support is used both as a desktop or on his lap and onto the bed? I was surprised by the inclination of the support which allows good keyboard input. -3 Speeds for the fan that regulates the energy consumed according to the activity that is running on his computer. -I Have not yet fully realized the refreshing impact induced by the fan, but at least I'm sure on a bed, the air intake of the laptop is not blocked by the cover or something . Pleasant -Aesthetics, mobile is seized to the support. Delivery -Delay amazing, ordered the afternoon at 16h, received the next morning at 10 am in control "fast"
