Raptor M45 in all its glory
Being primarily designed for FPS usage, M45 is better suited to the claw grip because of its physical dimensions and shape. Unlike other mice which are ambidextrous, M45 is tailored towards right-handed gamers only.
Corsair has used two different material types for M45 – the top is covered in a smooth matt plastic which is durable and soft whilst the sides are adorned in a gritty, non-slip textured material to prevent the hand slipping away from the mouse during extended gaming sessions.

Two buttons for thumb point to right-handed only mouse
M45 has seven programmable buttons and two of these can be found on the left of the mouse. These buttons have been intentionally placed for the thumb to make use of and are customary for most mice nowadays – being typically used as forwards and backwards navigators.
At the front of M45 the cord can be seen trailing from underneath the left mouse button. In the middle there is a large scrolling wheel which has a ridged rubber surface. This scrolling wheel snaps to increments and requires more force than we would usually find on a gaming mouse. Directly above this wheel there is an LED indicator for the DPI sensitivity and two buttons to increase or decrease this setting. The DPI is represented by a simple line and the actual sensitivities can be modified to your liking within the Corsair mouse software.

The underside of M45
Flipping M45 over and looking at the underside we have plenty of features to talk about. First of all, the cord which gives you connectivity is braided for extra strength and the USB connector is red to help distinguish it from other connectors that might be plugged into your computer.
Corsair has given M45 five PTFE glide pads which are replaceable. These pads are positioned in key areas to assist with smooth and accurate motion.
At the heart of M45 is the Pixart PWM 3310 optical sensor which is optimised for FPS games. This sensor uses Infrared and has detection up to 130 inches per second with 30g of motion detection. DPI is also versatile, allowing sensitivity from 50 to 5000. Corsair state that this sensor is better suited to cloth pads, in the next section of this review we’ll report back on how M45 responds to different surface pads.
Also on the bottom of M45 are a trio of weights which allows the user to choose whether they want the mouse to be light or heavy. A screw helps to conceal the individual weights – each screw is 1.5g whilst the weights are 4g each. We like the idea of being able to customise the mouse in this manner, often mice can be too light or too heavy and the weight cannot be altered but with M45 this isn’t an issue thanks to this handy and innovative set of features.
