With other fans I still had abrupt shut downs and had to constantly feel bottom of laptop to ensure I wouldn't lose data to a shutdown. I have had for a couple months now and not once has my computer shutdown or gotten really hot. I would recommend this fan to all laptop users that had shutdowns due to excessive heat and STAY AWAY from the little fans (even if they have 3 4). The large fan is the only way to go.
Another note I am very hard on my equipment and use my laptop for 10 12 hours each day. Moving around, banging, dropping things, adding devices, programs, trying products, etc. This fan has held up to all my torture, so if you purchase you shouldn't be disappointed.

Purchased this product to use with my Macbook. From the first time it was used I had problems with this item. First the fan would not start. Then when it started it was very noisy, plus it has the hard plastic legs that would dig into your lap when putting this on your lap with computer. After a couple of weeks I disposed of this item. Not the most effective cooling pad.Read Best Reviews of Manhattan 200 mm Notebook Computer Cooling Pad (703406) Here
I purchased this to test on two devices with the intention of buying a second if it works as hoped.First I tested this under an Acer Aspire Quad Core 7551-7422 laptop. It has some over heating issues when the side vents are not at the edge of a table and occasionally shuts off due to heat build up when using graphically intensive programs. I placed underneath it this cooling pad and plugged it into a USB port. The fan was quieter than the internal fan of the laptop, and after a day of use the bottom of the laptop was still cool to the touch. Although I was initially concerned that the laptop was wider than the cooling pad, it turns out that having the laptop wider was an advantage as the laptop's own vents were raised up allowing for maximum airflow. As an added bonus, the USB cable had an adapter on top to plug another USB cable into it just in case I needed it, but I didn't so can't say how well this feature works with hard drives and such.
I then tested this under my Playstation 3 console. A Fat 1st generation Playstation 3. Although mine has cooling mods applied already, heat is still a potential problem. I had someone else place this under the console while I picked it up (since the console is 14 pounds) and decided to plug the fan into a USB to power adapter. I couldn't hear the cooling fan at all compared to the fan of the console, so at first I wasn't sure if it was working but it was! I was concerned at first because there isn't much of a gap between the table and the buttom of the pad in the front, but after a day of use the bottom of the console was still cool. When the console is turned off the fan continues to run because I had it plugged into a power outlet, and the sound of the fan is still so quiet you barely notice it.
My poor laptop overheated again without the cooling pad under it (while testing it with the Playstation 3) so I fully intend to purchase a second one for me, and will likely buy a third as a gift.

I bought this to set my Mac Mini 2010 on. The CPU had been topping 160F and froze the Mac with a fault a few times. Now the CPU seems to stay between 145F and the low 150Fs. So far, no more shutdowns. The fan is quiet, and large, though slow. It does come with a handy but optional USB pass-through plug so it doesn't actually reduce the number of USB Ports. It has a low angle. so the Mac doesn't want to slide off (though it does have 3M Sorbothane Hemisphere Rubber Bumper Non-skid Feet that raise it up and prevent slipping).The negatives are that it's mostly very thin and fragile looking plastic, and the feet won't stay on since there is barely any plastic for them to stick to on the hollow round legs.
It is about an inch tall, so if you're using it with a laptop you won't be able to rest your wrists on the desk and type.
For my needs, I am very happy with this fan.Overall this is the best fan I have found. I use it under stereo equipment to keep it cool. This fan moves way more air than any other fan I have tried, yet it is very quiet. Two things to note though. First it is not level (the front legs are shorter than the back), so I have to place something under the front legs so that my stereo equipment remains level. This wouldn't be a problem for laptop users. Second, it has four rubber pads on the top and four more attached to the legs on the bottom. The legs have very little surface area where the pads attach and the pads don't stick well. Two had come off if the box when the fan arrived. This is not a problem for me, but I think it would be a problem for some laptop users; if you are not using this on a desk or table and always leaving it in the same place, the pads will probably get lost. The legs would also be very uncomfortable (even with the pads) if you actually tried to work with the laptop on your lap while using this.
