The thumb buttons are convenient, the scroll wheel is chunky which gives a lot of control. This is crucial as this is for panning in CAD.
Switches are both OMRON D20-1F, which are what the majority of gaming mouse uses. The pinky rest and thumb rest are godly.
3 level of sensitivity.
Auto-turn off.
Comes with a wireless dongle that's easily replaceable, unlike big company's proprietary ones.
It comes with ok mouse feet, but these can be changed to teflon cheaply.
It's really light, but I manged to fit stacks of coins within the shell, to a point it got too heavy.
I just can't think of what justifies the extra cost.
Sometimes this mouse drops to 8 pounds, which is $11.4
