Pros: It works.

Cons: Would be if it didn't work.

Overall Review: It works.

Pros: - Very light and responsive. Smooth to operate - Comfortable, especially for a fingertip grip like mine - Good price- much less expensive than other gaming mice

Cons: - I'm not crazy about the placement of the forward/back buttons and have found myself accidentally pressing them. They are also not prominent which make them harder to feel around for. May just take some getting use to

Overall Review: I had a Razer Imperator mouse for several years. Then a Corsair Glaive for several years. This mouse is less expensive and has all the same features. It doesn't look like a spaceship like some of the more expensive gaming mice.

Pros: - Good build quality, ergonomics and main button / scroll wheel feel - Very lightweight, perfect for claw grip - Great sensor - Tasteful RGB lighting (scroll wheel only) - Inexpensive

Cons: - Did not work out of the box on USB2 ports for me (see below) - iCue bloatware needs to run to remap buttons (not stored in hardware like lighting profiles) - Side buttons are a bit loose, could be a tad better

Overall Review: Got this to replace an aging Logitech G1; the shape, weight and ergonomics are very similar but not exactly the same (eg : no borders around the main buttons so misclicks might be possible if your fingers rest on them). The main buttons and scroll wheel feel great, though the side buttons do feel a bit cheap (loose) to me. In the end that's definitely good build quality overall for the price. Out of the box, the mouse did not work when plugged in my USB 2.0 ports ("Device did not start" error in device manager). However, it did work when plugged in an USB3 port and after a firmware update in iCue it now works when plugged back on USB 2.0, even with 1000Hz polling and RGB lighting active. Speaking of iCue, unless you're in the whole Corsair ecosystem it's quite bloated IMO (700MB download, 2GB install, 300-500MB RAM usage with a bunch of background services) if you just want to manage a mouse. You can store a lighting preset in hardware that can run with iCue disabled, but do need it running if you remap buttons. I might look in a lighter 3rd party app instead like X-Mouse Button Control to do the latter.
