I was extremely happy with this wire less mouse. The first reason was because the connector is located in the mouse itself. I cannot tell you how many I have lost because I end up laying them on the table and they go missing. The other reason I am giving them a 5 star is because the mouse is small not bulky I have carpal tunnel and it's hard to grasp and hold on to things. This is perfect for my hand. And finial reason, I recieved an email and they offered me a mouse pad for 99% off you cant beat that! #RankBoosterReview #awesomedeals
