I live in a hot state and have to make sure my laptop does not overheat. I deal with it every single year. Well this year I can stop worrying now that I have this great riser. You can raise it 3 levels to keep the bottom of your device cooler. Super easy to put together. Just screw in the legs. I did need to gule in the rubber inserts in the legs and they wanted to fall out, but thats only because I put my device in my lap. Other that that this is perfect!
