The cooler is well thought out and rather well finished. But only downslope two small rubber studs to hold the laptop. It also has anti-slip studs on the underside, obviously not right in the same place as the cooler, it allows the laptop to quietly slip over rubber spikes retarder !!! At best to fall in your lap if you use it on your lap. On a table, it may fall down! Indispensable to add a DIY yourself to avoid the fall of the laptop! Or place the very down the table edge :-)
