I have been using high end Logitech wireless mice for years, and I'm noticing a pattern. After about 2-3 years, the mouse starts issuing false double-clicks, or letting go when I'm drag-and-dropping. It's now happening with my G700, after it happened with my G7 and one other mouse. It's really irritating to have your workflow impeded by not being able to mouse properly. Why does this happen? What should I replace my G700 with? I might just buy another G700 if they're still available, despite the degradation.I use the mice so much I can hardly blame them for breaking down.
