I recommend it for everyone.its very good.product come in sealed.the succession power is good.it adjust along with your heat in your laptop. temperature difference is 10-15 degree. my laptop gets heated and it got shut down automatically.now the problem is solved.i am happy with it.though my laptop heats but it cools soon while using it. it has one cons i.e. every time while on it i need to adjust it manually. otherwise product is very good and works well. I recommend it for everyone with laptop heating problems.

Pros1. Compact, easy to understand2. Cools down your laptop under continuous stressCons1. For this price, there could have been holding pins at the bottom as well for perfect fit onto laptop. This however is an issue for all coolers present at Amazon and this currently does a better job than most2. Needs open ventilation and cool air presence at laptop intake to perform efficiently3. A bit pricey for just a powerful version ventilation fan.I bought this product for the sole reason of increasing my laptop ventilation. However, since its pulling hot air out, either the room should be cool, or some amount of cool air should be present around the intake vents at the bottom of laptop for it to cool down really well.Initially my laptop was still a bit hot until I placed it atop a laptop cooler pad which provided a bit of cool air to the intake vents. That did the trick and now my laptop temperatures have fallen dramatically from how it was heating up while gaming etc.Cooler + Laptop Pad = RecommendedRating 8/10

Not much useful as it didn't remove heat completely and is also louder. Had to buy other Cool Pad with 4 fans at bottome, which is performing better than this in both cooling and is very less sound.

I had a cheap chinese vacuum cooler before buying this one called "Gadgetbucket UnTech Cool Speed Adjustable Portable Laptop USB Cooling Fan" available on amazon. That cooler was working excellently but I had to STICK its rubber piece to the laptop with a tape for creating proper vacuum. After that it reduced the temperature upto 8 degree celcius, provided the room temperature is cool enough. I mean if you are gaming on a laptop in a 45 degree celcius room, then vacuum coolers won't be able to reduce more than a couple of degrees.Then I decided to buy an expensive vacuum cooler thinking that maybe expensive ones will do a better job. This OFFBEAT vacuum cooler is better at creating vacuum because of its screws and base plate. But that's where its advantages stop. Somehow its cooler power is even LESSER THAN that chinese one, maybe because of a tiny, congested air inlet. I have tried with multiple games to confirm this, the basic chinese one (the one in the first para) was always able to reduce 2-4 degrees MORE compared to this Offbeat one.Hence I would suggest everyone to buy that chinese one for cheap, some sellers are selling that exact same chinese one for a price of Rs. 1000 or more which is totally unjustified. Don't pay more than 600 for that under any condition. You will have to use a paper (medical) tape to stick its rubber mount onto the laptop then it will work flawlessly.

In 2018, my trusty old Acer laptop started overheating, and as a last resort before buying a new laptop, I bought one of those cheap 'Tarkan' vacuum coolers. I thought that the worst case scenario would be a waste of 900 bucks, but much to my surprise, it actually prevented my laptop from overheating (reduced the core temperatures from 90 to around 65 degrees Celsius).So when that old cooler stopped working a week ago, I decided to buy a new one, and on impulse, thought I'd try this more expensive unit since the reviews were good. Bad idea.It. Does. Not. Work. At all.I noticed that the plastic base plate provided tends to block a ventilation port at the bottom of the laptop, so I tried the running this cooler both with and without the base plate installed. But no luck. Within 10 minutes, the processor temperatures had crossed 70 degrees Celsius.Here is the funny part: I tried running the cooler without connecting it to anything, and after a few minutes, the exhaust air was noticeably hotter than ambient temperature, even though it wasn't attached to a laptop! So it appears that the cooler is heating up on its own, so if anything, it is probably making things worse.On the plus side, the screw contraption is actually effective at keeping the cooler secured to the laptop, but the flipside is that you need to stick the base plate to the laptop to achieve this. Then the base plate juts out awkwardly from the bottom of the laptop, and when you want to pack the laptop in a backpack or bag, it will either not fit because of the protruding base plate, or the plate will snap off during handling. Probably both.The other positive is that it runs fairly quietly (still new, don't know how noisy it might get after a few weeks) and the fan RPM is noticeably higher than on my old unit. Sadly, ALL of these positives are completely inconsequential since it doesn't perform its primary function of cooling the laptop effectively.As with all of these cheap things, depending on the specific laptop you use, your results may vary. But my advice to you is, don't bother with this one. The cheaper thing seemed to actually work better than this.

I was using a laptop cooler before for playing games but it was not sufficient to keep my games from lagging. So I decided to buy this so I could use both laptop cooler and laptop heat extractor. But soon I realised that while using this I don't need my laptop cooler at all, this does the work efficiently n keeps my laptop much cooler than before and best of all it holds on to the laptop while moving.Much smaller n portable than laptop cooler and much much better in keeping the laptop cool. Gamers go for it highly recommended.
