Nevertheless, I have to say the performance is very good, whom I turn the extra cooling fan stops my Macbook so hot that it will slow down (although the fan is not optimal).
Since you can also adjust the angle of inclination, it is more pleasant to work on the laptop as without such backing.
The size is also more suitable for 15-inch laptops as my little 13 incher but I since I have consciously decided what Larger, because thus my friend the fan can also be used.
As a test I have my Mac normally used simultaneously opened and worked with it (Internet, Word, Photoshop, iTunes), without Cooling Lounge runs hot after 30 minutes and will be noticeably slower. It happens that I have to close programs.
Connected with Cooling Lounge, it is even warm but I have so far no need to close the program. Therefore, I do not know if my laptop is really much cooler, but because it runs better I go away from time.
Conclusion: I would buy me the next time a cooling pad where I can even rearrange the fan or these are further back.
But if it is a Windows, I would immediately grab again for this or a newer Belkin Cooling Pad the brand.
