The mouse is considered to be quite light at about 92.1 grams and comes with a black matte plastic shell that does not collect fingerprints. Its shape was designed in order to accommodate fingertip or claw grip types, while the top button near the scroll wheel is initially programmed for easy DPI switching:

In the back area of the mouse shell we will get to see a RGB-enabled logo:

On the left area, the manufacturer has included two programmable buttons, along with a thick pure silicone side grip:

Since we are talking about an ambidextrous model, the right side is built exactly the same:

In the front, we’ve got the two-usual left/right click buttons which do feature split-trigger switches (Omron, rated for 50 million clicks), meaning that they are separated from the rest of the back shell. This type of design is meant to provide an optimal experience during rapid clicks, button holds or burst firing. Also, we need to mention of the rubberized scroll wheel, which is silent when actuated and is also RGB-enabled:

On the bottom area of the mouse, we can see the PTFE feet in the corners, along with the central TrueMove3 optical sensor lens. The new sensor was built upon the base of the Pixart 3360 and now does feature 1:1 true tracking capabilities, very low latency, advanced jitter reduction but also a custom firmware for increasing the sensor accuracy timing. The sensor DPI can be adjusted from 100 to 12000, in 100 DPI increments:

For an unknown reason, SteelSeries did not choose to go with a braided cable this time:

The USB connector does feature a thin design and we can also spot a sticker attached to it which informs the user to download the dedicated software in order to be able to control all the Sensei 310 features:
