Best mouse ever, but still has problems
on November 27, 2017
This mouse has the best form-factor of any ever created in my opinion. It's my go-to mouse for every computer. It's the same as the MX-500 and MX-518. However, this mouse suffers the same problems as the previous models - the cord is too thin and wears out at BOTH the mouse and the USB end. The middle-mouse actuator switch (the click you hear when you press down on the mouse wheel) wears out, as does the DPI-UP and the window-toggle button.
I now own 6 of these - all of which (except the latest) have had their cords replaced and resoldered, and some of which have had the aforementioned switches replaced and resoldered.
Also, the pads on the bottom wear off very quickly and the rubberized finish on the sides also wears off after a few months/years.
THAT SAID, the "logitech gaming software" (button mapping driver utility) is awesome, the mouse fits perfectly in the hand, it has the perfect weight, the switches are the perfect sensitivity, the red sensor on the bottom works on basically any surface (frankly the new laser sensors are terrible, this mouse is much better), and it has a really nice number of buttons (not too many, not too few).
