Q: The last thing you expect is to receive a product that simply does not work. It happened with the fan of the cooler master hyper 212. It simply would not work, probably a broken wire internally. Have tried to connect it to different power outputs in my mother board, but finally realized it was burned. Now I need a new fan, probably from a computer shop nearby.<br /><br />I wonder what kind of quality control they have at Cooler Master. I had them as 5 stars supplier for cooling stuff, but now i have to give it then no stars at all!<br /><br />Another thing that needs improvement is the installation instructions. It's very confusing, too much details and small fonts and illustrations. If you are not an experienced computer guru you will spend about an hour to figure out how to assemble it.

Q: Not impressed. Battery failed to charge after two weeks. Got an authorization to send it to Asus, and when they sent it back, &#34;repaired&#34;, it would not turn on. Shipped it back to Amazon for a full refund. Since then I've seen this puppy for $299 on Groupon. Don't waste your time or money. The upside is the ASUS employee I spoke to was very courteous, and sounded Amaerican. Unfortunately they can neither make, nor repair a tablet computer.

Q: At first I had my USB receiver plugged into the back of my desktop (10 feet away, but blocked by sub-woofer and coffee table) and was having issues with a lag with the keyboard, I did not have a problem with mouse reception without direct line of site.<br /><br />I found a little 2 foot USB extension to point the receiver in my general direction while minimizing obstructions and haven't had any other problems with lag.<br /><br />Just keep in mind that you will need a 80-90% clear line of site between keyboard and receiver.
