-Nice looking -Good weight (not light, but I like a heavy mouse) -Thumb and pinky finger rests are fantastic -Wireless feature works great as bluetooth or WIFI fob with no noticeable latency

Scroll wheel has gone twice in 3 months. Will no longer scroll, or will scroll in the opposite direction for a tick or two. Very frustrating. The first instance I let slide and warrantied it (paying for shipping). I was without this mouse for weeks. The second instance caused me to disassemble the mouse to find poor contact with the scroll shaft (cheap plastic) not registering with the scroll detector. Moving the shaft further out from the detector solves this, but I cannot get it to stay in that position as any middle mouse clicks kind of reset the shaft back. I am done with this overpriced LED junk. Back to Logitech 502 ($50) which lasted 6 years before "upgrading" to the corsair darkcore pro ($120). Cheap switch for middle mouse button gets very loose very fast, making it easy to mis-click middle mouse.

Just don't.

Good features, works with wireless dongle, bluetooth or USB

Very low quality mouse. Scroll wheel is the weakest point (when it worked). Now scroll wheel wheel jumps randomly. Common problem with Corsair mice.

Went back to my 8 year old Logitech mouse and works perfectly. Will never buy a Corsair mouse again after this. Talk about buyers remorse, $130 dollars down the drain. Should have stuck with Logitech!
