This is the second wireless mouse I've owned. The first time I purchased one I bought a high-end Rocketfish wireless mouse. It was all right, but I felt it lagged a bit with response time. At the time, I was on an "insurance budget", meaning that I was shopping on reimbursement money from insurance (home burglary). So I was trying to stay within the allotted amount. The wireless mouse I bought is a Kensington. Honestly, I didn't know anything about the brand name, but I tend to be in the dark about a lot of "names" in the technology field. It was the cheapest (money-wise) mouse the electronics store had. That made me think it probably wouldn't last for long.
When I took it out of the box, I was pleasantly surprised by it's sleek look! It has a scroll wheel, and the color is cranberry with circle designs on it. I installed 2 AA batteries inside the mouse, and plugged the sensor into the USB port. That's all it took to get it up and running. When I use this Kensington mouse, the motions are so much smoother than my last mouse. No more jerky, delayed movement navigating on my laptop! Wow! For the price, I feel like I got an exceptional wireless mouse!
