As efficient as ever
After a year and a half of use, the mouse is still working and at 90% of its capacity, only the left click is starting to get a bit hard (you have to press a bit harder now), but that's normal as I use it all the time in competitive games. The cable is too light, you hardly feel it, plus you can unplug it, a cable like that avoids the problems of cables that go haywire after a few months of use. I bought it at half price so it's really 100% win win.
