Fits just about on the rubber feet of my 17" MSI gaming laptop. I'm happy with that, but the sticky pad is overkill. Are you sure you want to block those bottom vents? You could fix this by making the platter the same size as the top, 11 x 15.5". One more thing: be careful when leaning on it, as it only offers limited weight support once you have your computer have relied on it.All in all this is a great product for a large laptop and works as expected.
