I have not had this cooler for very long and it's my first laptop coolers ever but I can already say that it works really good. My laptop just was not fully operational before without lowering the processor speed by 60% +, I did not it was the laptop overheated during normal operation, but with this cooler is no problem, the laptop becomes almost cold! Aluminum upper material is a big advantage if you have a little cool in the room when the surface becomes icy, which also helps cooling. I do not know how it works in the summer but I doubt whether there will be any problems, but it can certainly produce the opposite effect.
The fan runs on top of my case, but it is not louder than my PC or my laptop's own fan, it is even so that the noise level on the laptop's fan running at full speed is at least three times as high, and it is still not the heat down to an acceptable level! Thanks to the holes in the plate so it can also be used as a passive cooler (before I bought this cooler, I had the laptop on a book case I spill on the table, then I put a box in the computer to get a gap between the laptop and the surface it standing on, and just did a lot of difference so this surface is even more open plus its materials should make a big difference).
It is easy to use, cord included are short to not be distracting (plate and its active functions powered by your USB port), but I want to point out that it only seems to have an input on the left side, which means that if you have your USB ports on the right side, you will need to have a longer, separate cord, but that is standard with ports on the left, or you can plug in your computer, on both ports (includes a USB hub that sits on the right side ), however, can not test this right now, it's whatever worth knowing about!
Some disadvantages are that it is quite big and it weighs a lot, I bought my laptop because it was smooth yet powerful (13 "screen), as this cooler destroys a little bit, but it's still good to have my PC on something , just in case you spill any liquid, and the computer becomes too hot it becomes. Others can be said that is negative is that it has a fairly sharp blue light indicates that the plate is turned on, which is a pain if you sleep with it on, or have it inside the TV room or so. device can also be tricky to wear a bare knee or leg when it gets cold, and that the fan's wind can be detected, this could probably be a bit of a deal-breaker for many, since many looking for things like this to the laptop gets too hot to wear the knee, but unfortunately this can become a problem instead of a solution, although I only tried to put his hand under the plate, but it was not very nice for longer moments, so it may be worth exploring, perhaps by going naked at any computer store and just run, who knows ;)
Otherwise, it gives pad your laptop a very pleasant slope, which causes it to become higher than the keyboard, this gradient is built in and can not be disposed of, but it can be extended with some plastic pegs in the rear. The plate also provides a generally comfortable height increase, which can be great if you have a low coffee table or similar.
In summary, this laptop cooler excellent, it does its job and then some, can easily recommend it, however, read the full review for there are some things that many may disturb on which you should know about before you purchase this product!
