I'm not sure why manufacturers think they can just slap some LED's on anything and it'll pass. Maybe 10 years ago, but not anymore folks. And honestly, who uses 40mm fans anymore? They are utterly useless in every area. This product is called a notebook cooler and that's a stretch of the use of the category. If by simply tilting up the rear of your laptop enables itself to cool better (as it would with virtually every laptop on the market), then I suppose you could loosely call this a cooler. However you need a smoke stream to see if the air is even moving (even on "high" power). I bet this unit could be redesigned as a wireless notebook cooler, and with those tiny fans and no airflow, it should run for weeks on a couple of AA batteries.
