wireless mouse

This is a little late but I just installed a wireless mouse on my Inspiron 5160 and I love it. I found a MICRO INNOVATIONS mouse at Wal-Mart in their discount section. It has a cradle that acts as a receiver plus a mini receiver. Both receivers plug into a USB port. Charge the batteries, load the software, and plug the receiver in. Windows will discover it and you are ready to go. I accidently set the mouse in "off" when I installed the software for the mini-receiver but after that it worked great.
