"Everything I Needed"
This thing works great: the channels in the top help with airflow, little rubber feet on the top lift the laptop above the surface, and the fans are extremely quiet. The USB hub works just fine and the unit can be powered by its own AC adapter, but I typically just let the USB cable power it. Because it's a bit smaller than my Dell Inspiron 8200 (15.4" screen), it packs neatly into my laptop backpack. The cable is short, easy to stow, and easy to connect/disconnect. Last, I've had it for a year now, and although it gets crushed every time I pack it away, it hasn't had any problems continuing to run. Highly recommended for anyone with a laptop that has a 15" screen (anything bigger and you might want a larger size cooler)

"Works, with a few kinks"
Good buy, it worked really well the first 2 odd weeks I had it and then the fans started making a lot of noise (hitting the casing) and its really hard to remedy that - you have to mess around with it for 15 minutes till they stop making the noise and then not move it to make sure they stay like that. Other than that, it blows air AT your laptop, not away from like I expected it to, but maybe thats just what I thought it would do.

All in all the USB hub is really a nice feature to have in here - makes this thing like a dock, just way cheaper. Buy it if you will, but make sure you get some order of warranty or be prepared to send it back soon if the fans start making any noise.

"Works well"
I'm only giving this 4 stars because these things are just too damn expensive, otherwise it would be 5 stars. Without this my 17" Dell Inspiron 9300 can cook eggs. This draws the heat away and keeps the bottom cool, which is what it's supposed to do. I haven't tried the USB ports, my laptop has 6 already. I recommend this product for anyone with a portable heater for a laptop.

"Great product, great price!"
This is the best price I could find on a chill HUB (with 4 USB ports!) and so far so good! It is keeping my HP Pavilion notebook nice and cool. There's an on/off switch, and the fans are nice and quiet. It comes with an AC adapter, but as long as you have your laptop plugged in, you don't need to use it. It runs just by connecting it with the USB cord (which is nice and short). It is a little small - fits my 14 inch laptop just fine, but anything larger would be hanging a bit over the edges. I definitely recommend this product!

"Effective, but too LOUD"
Somehow, I thought that a product made to work with a laptop would be fairly quiet, or at least offer variable speed so that most of the time it would whisper. I played with this for about 10 minutes and will now just put it on eBay... it makes a quiet MacBook Pro sound like an old PC while raising it to an uncomfortable height. Fellow Mac users, try this first: smcFanControl (Google it). It's an app that lets you set the minimum fan speed, and has dropped my average CPU temp by about 15 degrees. I found it after ordering the Chillhub.

Later note: Although loud, I have reached for this a couple of times when the laptop is working hard and heating up, and it DOES cool very dramatically. I just wish it had a speed control.
