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.

This Roocase is the best , great quality product, I love how you can take it out to hold it, then when you put it away in its zipperd case it's very well protected. I bought one last year for my kindle fire. JUST LOVE IT

When I ordered this case, I was ordering it for my wife. She didn't exactly know what she wanted, except something to protect her new Kindle Fire. I didn't want to spend a lot of money until she knew more about what she wanted in a case. It was a hit. She really liked it, I didn't have to spend a lot of money for something she wouldn't like, and great quality for price.
