Flexibility Makes Pleasure

My friend asked me to help him choosing a wireless keyboard for his new desktop, so I suggested him to buy Logitech EX110. Logitech is my favorite brand in wireless keyboard and mouse. I choose this EX110 because it is the cheapest cordless desktop that produced by Logitech but have good quality. There are many cheaper wireless keyboard (China brand), but it is no good for long term using. This EX110 has built-in keys for multimedia and internet to make user easy to access to that function. The buttons also so smooth (does not make any noise when I type words). The wireless mouse has a good precision and a perfect shape for my hand. To run this device, I use 2 AAA batteries for keyboard and 2 AA batteries for the mouse. The battery consumption is good. My friend said that he never change the batteries since the first time he bought this cordless keyboard (two months ago). The range is two meters at maximum, so he can do his works from bed, but with a big screen of LCD of course. However, the disadvantage of this device is that it cannot be use to play "serious" game that requires 3D such "Need for Speed, FEAR 2, etc", because the precision is not good and sometimes it gets no response. In fact, all cordless desktop is not recommended for playing "heavy" games.
