Pros: Cools down the laptop somewhat while it still works.

Cons: Horrible wiring, broke after less than 4 months.

Overall Review: After about 3 months of use, the socket fell in; disabling the fan. Needed to open it up two or three times a day for the next two weeks to push the socket back in place until the wires finally ripped off the connector, rendering it unusable garbage. Will not be buying this again.
