snake oil probably, you cant really suck out the heat tbh

look up convection
If it's USB powered, I can't see this doing much besides creating a lot of noise. Anything USB powered is going to be weak.
it sucks out more air than the internal laptop fan can blow
"suck and blow"
where are the jokes?
Real deal for real branded one , not sure about this no brand self proclaimed patented design though
i got a branded one from "Evercool" legit company , it works on cooling down my overheating acer which no longer auto-shutdown when on use.
the vent blows out much more air than before
self proclaimed patented design
where does it say it's "patented?"
In theory wouldn't this cause negative airflow, and dust to build up inside your case?
Their user submitted video review for the product at the bottom of the page shows it seems like snake oil.

Are they PATENED [sic] though ???
Does it work?
yes , refer above
Yes and no. But one thing you could be sure of, is that it's a waste of money.
Yes, you can "suck air" out of the laptop. But for it to be done effectively, you need to create a tight seal from the fan all the way to the laptops intake (doesn't seem like they've even bothered to address that) otherwise you lose all the pressure (a.k.a sucking power) to the surrounding area around the fan. So you're already at a disadvantage when compared to something blowing air into the computer. To make matters worse, if you already have a working fan, unless it is somehow able to out do your laptops fan at max, you are just creating more friction. All laptops will also ramp up according to the temperature, so at best you might be able to see a little difference when your laptop fans are running at low speed (when your computer needs to be cooled the least) and this at high speed.
Only situation where i can see this being helpful is when your laptop is broken, in which case anything is better than nothing. Not exactly a high bar to beat.
TLDR: It's a waste of money and probably very loud too. If you want to cool down your laptop buy one of those cooling pads, they do a much better job. Or just open up your laptop, and clean out the built up dust that might be clogging up most of your intake
LANDFILL
i had a similar one of these attached to my old NEC laptop that had heating issues. it was cheap and did an okay job keeping the laptop a bit cooler until the replacement fan unit arrived.
i reckon cooling pads are a better alternative
Real deal or snake oil? At this price, I'm suspecting the latter. Hopefully it doesn't live up to the store's name when you plug it in.
