I hate being shaken down. This is an item you buy because you really need it. It's priced ridiculously high as a result.However, the device works better than any device I've tried. I own a MSI Prestige 15 laptop, which is very powerful and capable even today, but it got so HOT I was concerned it would bake itself, and I reduced CPU, GPU and other use, so I couldn't tap its' full capabilities.This device forces air thru the laptop faster than the laptop can take it. At full force, air starts coming out of holes in the laptop I didn't even know existed, including between the keys. It keeps the ENTIRE laptop cool, not just the key spots like the built in fans do.I can do heavy work all day long with the cooler's fan at 600, with acceptable noise level for office work. If I push the laptop extra hard, I've needed to crank the cooler ip to as much as 1400 at which point it's pretty loud.Given how expensive the laptop was, and/or how much it would cost to replace, it's worth the price for what should otherwise be a $25 item.
