I received this item within 3 days of ordering so, very speedy.
To clear up some confusion I had before buying, which I've seen many questions go unanswered...
It's complete dimensions are: 27cm x 23.5cm
I have a 17" widescreen laptop, and although at first it looks too big for it, the little rubber feet on the surface stop it slipping, sliding, wobbling or moving about at all and once you've got it in the centre of balance (keeping in mind the weight and placement of the screen when the lid is up), plus its at a wonderful angle for your neck and hands.
The fans, which it doesn't mention in the item description, actually draw the heat from the machine, not blow cold air onto.
And they are exposed on the underside of the cooler, so I wouldn't suggest using it on an actual lap..rather a solid surface like a desk, small bedtable or the like.
The noise is slight, but no more than you've expect from 3 little fans whirring around.
As of yet i can't comment on how effective it is (hence only 4 stars) because it's only been plugged into my usb port for 10 minutes and i have to go to work. But so far, so very good.
UPDATE - i've had the cooler switched on and doing its job for 7 hours straight and my laptop is almost ice cold, absolutely brilliant...considering it was seering hot after around an average of an hour's use.
I would seriously recommend this item! I would change to 5 stars if I could.
