Mostly a Really Good Mouse
Color: Silver, Style: 1-Pack
This mouse connected perfectly, feels good, and even works seamlessly with my cordless keyboard, which of course uses a different dongle. I have only one small issue, but it's one I thought worth mentioning. While the buttons work normally when moving the cursor around the screen, when it comes to actually making a selection with the primary button (right- or left-handed, doesn't matter), one must press the button VERY deliberately and somewhat slower for the "click" to be recognized. A typical "quick click" at the speed one would normally use, say, when typing or normal "mousing" often will not register with the computer. The result is that I have to slow down and click again. In several decades of using a computer mouse I've never experienced this phenomenon. I've grown used to it, however, and adjusted to the necessity to give the selection button a slower and harder "press" when making selections, and that's all it takes. And oddly, it only requires this extra deliberate action when pressing a selection button. Not the biggest issue one could have, but I thought it worth mentioning. Other than that, no problems, and really, the price is very good, so as they say, you pays your money and you makes your choice. ;-)

Works great.
Color: Silver, Style: 1-Pack
I have to edit my review: the mouse itself is still working fine, I happened to get a bad batch of Kirkland batteries! I changed out the batteries with a different brand and the mouse is working perfectly!! Didn't last very long, have only had it 3 1/2 months and it has stopped working.
