I tried other stands from Fellowes and Kensington and this is the only one that cuts the heat generated by my hot, hot Dell Inspiron. But it's bulky and a little heavy.It has nice gel padding underneath for that part that rests above your knees, and a gel pad in front that doubles as a wrist rest. Very comfortable once I get it on my lap.The other stands I tried were lightweight and collapsible but did little to reduce the heat.The iLap cuts the heat I would estimate by 90%, which is well above the others I tried. After a while, it feels a little heavy on my lap but then my notebook is pretty heavy by itself.
