I brought a brand new one from my friend and I loved to have one. As my work with computer is increasing every day, I decided to work from a distance in order to save my self from getting eye damage and for that I brought this cordless desktop. It was a good one but not appreciable one. First of all what I liked most about this is, the distance from which it was working. It worked even from a distance of 20feed from the receiver. Also the keyboard is designed well and the optical mouse is light. The keyboard is a bit heavy and mouse if perfect. The speed is also good but not that appreciable. Now coming to the disadvantages, the batteries are loosing power very quickly and it needs a frequent replacement for batteries. The keyboard is good which is giving more life for the batteries but the mouse working just for 3 to 4 days. Hence it is good for those who are using rechargeable batteries. Even I am also using rechargeable batteries and hence I like my cordless keyboard and mouse.
