I purchased a HP Wireless Mobile Mouse (Model LK006AA) after connecting my LED TV monitor to my PC in the living room. I love watching movies or playing games on a big monitor so getting a wireless mouse was definitely convenient. This mouse is comfortable to use, easy to set up, the battery (1 AA battery ) is easy to change and lasts for a long time. It has an off button so you can save on battery life when you're not using the mouse.
