[This review was collected as part of a promotion.] Just bought this mouse around a week ago, to replace my old mouse.
Very compact feel to it, it's compact shape such that my "medium-sized" hands can actually hold the entire mouse if I use a palm grip. (I mainly use a claw grip feels pretty exceptional, GRANTED YOUR HANDS ARE NOT LARGE) If you consider yourself to have large hands, you might be better off with a different mouse.
One of the nice features is how light it feels. Really do like how effortlessly you can move the mouse.
Mainly bought it bought it to replace my old gaming mouse (like a generic brand gaming mouse I used for like 4+ years).
Once of the reviews here mentions how they don't like the RGB, which is why you never throw out the manuals. All you gotta do is download the Legion Accessory Central (Pretty lightweight load I think, when you compare it to Steel Series or even Razer's clients) Mouse really begins to shine here.
Bunch of features, here are the notable ones:
Change RBG colors
Set up "mouse actions" (so you can set your any of the buttons to do macros, regular mouse functions (left, right click etc) volume up on media, just to name a few.
You switch DPI profiles by pressing a button on the mouse, or going into the L.A.C and specifically customizing them,
Selectable DPI from 200-8000,
Selectable Polling Rate from 125 Hz to 1000 Hz
As well as device firmware updates
Going to say this one more time, I really do love how light the mouse is (~57 grams).
