Corsair Vengeance K90 & M90 MMO/RTS Keyboard and Mouse Review

Just like the K90 bundle, the Corsair Vengeance M90 laser mouse comes with a warranty guide and quickstart guide. Once again you have to download the free software from Corsair to configure the advanced options.

Unlike many of the FPS fat body mouses, the K90 is a normal width (2.75″ across bottom and 2.25″ across the top) ergonomic mouse. Be warned if you have big hands like me this mouse is slender and a bit hard to grab. The body has a smooth rubberized coating that fits right into the palm of your right hand, leftys this mouse is probably not for you. There is a large metal scroll wheel with a ribbed rubber middle that also allows third button clicks but no side to side scrolling. The left and right click buttons are on either side of the mouse with a configurable button in the middle. On the left leading edge are two more configurable buttons that default to DPI increase or decrease.

We grabbed this marketing image from Corsair to show the LED lighting when active. There is a matching blue glow to the K90 LEDs from under the middle wheel, the middle button, and the up down arrow keys. The Corsair logo lights up white when powered up. The software lets you turn these lights on or off if you prefer a dim room.

The left side of the Corsair Vengeance M90 is truly the business end of this input device with no less than 9 buttons not counting the top arrow buttons. I have to say I was slightly intimidated with so many buttons and again you can see how a lefty might have a hard time adapting to this mouse. All 15 of the buttons on the M90 are fully configurable to run macros, typical mouse keys, or any other input function. Also notice the nice metal accent along the bottom of the mouse with the angle matching that of the bottom edge of the K90 keyboard.

The nose of the M90 has the left and right click buttons and scroll wheel terminate into a nice thick piece of aluminum for a very sleek look.

The left side of the the Corsair Vengeance M90 laser mouse is free of buttons with only a molded indent to rest your fingers or side of your hand depending on how you grasp your mouse. For my large hands it was this part that gave my hand fatigue after long gaming sessions. Smaller hand people might find this a non-issue.

The bottom of the mouse is a beautiful milled piece of aluminum and it is too bad it is on the bottom out of sight. In the middle of this metal plate is the 5700 DPI Avago Technologies ADNS-9500 LaserStream Gaming Sensor. Along the edges of the Vengeance M90 are the ultra low friction PTFE pads to make it easy to glide on most surfaces.
