CM Storm SF-19 - Large Gaming Laptop Cooling Pad with Dual 140 mm Turbine Fans and Multicolor LED Lighting

Pros: Got this to replace another Cooler Master Unit that was not working as well as I wanted. This one puts out great air, and keeps a Core I3 or Core I5 laptop cool. This is a heavy duty cooler, you won't want to sit with this on your lap. It's made for cooling a serious laptop. Works great with my Dell 17".

Cons: Fan on high speed is a little noisey, and does have a little vibration on high speed, but so far no fan failures and I need the cool air.

Overall Review: Worth the money. Don't waste your time with the othe brands.

Pros: Excellent Cooling
High Fan RPM was is achieved off of a 12V .75A External Power Supply (which frees up USB devices to power themselves off of the USB bus).
4x USB 2.0 Hub (eliminating the common problem of a lot of Laptop coolers: Lost USB port(s)).
Lighting is a nice touch.

Cons: Power connector inevitably fails. The input jack is bound to become loose after multiple disconnections and reconnections (which are bound to happen when you use the cooler as advertised and carry it (via handle) from location to location.
USB 2.0 Hub is not powered by A/C adapter and draws its power from the USB bus which can lead to power surges on the USB port or failure of devices to connect or turn on due to lack of power (i.e.: 2.5" HDD's, Rechargeable Video Game Controllers).

Overall Review: I debated over the long run whether to rate this with 3 stars or 4 stars. In the end I decided on 3. Although I've owned this more than a year, the fact that it failed due to an inherent design flaw for using a product as advertised (even sparingly) leads me to knock it down. I own 2 other cooling pads (Targus Feat. 4x USB 2.0 Hubs) which I have had for more than 3 years; each of them still work to this day.
