Bests & Worsts Reviews from Amazon

I bought this to replace my corded version, which had gotten banged up over time and needed replacing. I decided on the corded model previously so I never had to worry about a battery dying, or having any lag in mouse movement. I'm glad I decided to give this a try based on the prior reviews. Connecting it took no effort, as it was literally plug and play without having to go through any pairing process. It is just as responsive as the corded version, and I haven't noticed any lags or random pointer movement. As my attached picture shows, this has the same specs as the corded model. What is different is that the corded model has lights under the wheel as well as CPI button to give visual feedback of which CPI setting the mouse is set to. This does not have lights, but obviously for battery conservation. It's not hard to know which CPI setting its on, however. What's nice is that every time I boot the computer back up I don't have to go through the CPI settings again, as it remembers your preferred setting. You do have to click a mouse button to wake it up after a short period of non-use, but again...another battery conservation technique. What I do like better with this model, other than the obvious wirelessness, is that is has a little extra weight to it (thanks to the AA battery I'm sure) and a heavier click to make it feel more substantial. Hope this helps with your decision making!
