WIRELESS TRACKBALL M570

Today I found a best mouse for our use because we use those type of mouse if we want to move the cursor for performing any action on computer screen we move our hand or arms .according to my opinion this is a best mouse for our use because without movement of our arms by just rolling finger on the mouse ball cursor will move and we can perform any action easily. the design of the mouse is more comfortable for hand .
It is a without wire mouse and and it connect with our PC or laptop with the help of Bluetooth .
Price of muse is $49.99.
