Bests & Worsts Reviews from Amazon

5 months into my purchase and this mouse will stutter if it's not plugged in. On top of that I now have double clicking issues in any application. Tried going through Logitech customer support and I have to ship in this defective mouse before getting a new one. Which means going without a mouse. Which includes a 5-10 day period of waiting AFTER they receive it in order to get a replacement. The lifetime of Logitech products has gone down significantly. Having been a loyal customer of Logitech mice since the release of the MX518 it's extremely saddening to see the quality of products go down over the year. Specifically starting around the release of the g400 and g300 series mice. I'm going to step away from their products completely now.
