Logitech G502 is even better. The scroll wheel can be locked, which helps when scrolling through the huge classes as well as Android Studio translation files where CTRL+F doesn't work. The weight is better, and it solves that annoying issue with Razer where it's hard to sync the colors to my playlist.
There's just one problem with the Logitech: it sometimes registers a click as a double click and fails to drag items properly.
A minor issue between the two is I like to copy/paste with my thumb. The death adder's fourth and fifth mouse button is even better placed.
It was my brother's mouse who used it for gaming, and he said it failed as soon as he bought it. It works fine if I don't turn on the Logitech G HUB.
So THAT'S what that key does
I just wanna lay back on my chair, move my fingers/wrist + multitouch to control the cursor on the screen.
Too much pain.
And rarely able to replace a dying one with the same model.
First wireless mouse I've used with no perceptible lag.
The last 25 years I basically used mouses for right handed people. Currently it is the good old Logitech Performance MX.
