Like all current Corsair products, the NIGHTSWORD RGB comes in a black and yellow package, with the mouse picture on the front and technical specifications at back.
Inside we find the NIGHTSWORD RGB itself with a manual, a warranty guide and a weight case with 3 x 4.5g and 3 x 2.8 g weight blocks.
The first impression the NIGHTSWORD RGB looks very similar to the Logitech G502, maybe inspired by it perhaps but the Corsair NIGHTSWORD is a bit bigger and covered by rubberized surface. In the center is the Corsair logo, which lights up. Between the main buttons is a stylized rubber-covered scroll wheel, which is also RGB backlit. Any other contact surfaces, such as the LBM/RMB have a matte finish.
Besides the primary LBM/RMB buttons we also find two buttons on the left mouse button and two more under the scroll wheel. All can button be fully customizable on iCUE software.
The right side of the mouse is quite simple with a rubber insert on this side which ensures a solid grip, even with sweaty hands.
The left side of the NIGHTSWORD RGB is packed with extra buttons. At the front, three LEDs to indicate the selected profile and DPI. Above the wing with the rubber insert are a trio of buttons: forward, backward, and a sniper button.
The weight system is sophisticated as the mouse can calibrate its weight using a real-time center of the gravity detection system. With that said, the Nightsword RGB has an initial weight of 119 grams, and a total of 141 grams with all the weights installed.
The cable is 1.8 m long and fully braided with the USB connector does look like a pen-drive.
