The DM1 S2 is the successor of the DM1 Pro S, and shares its shape and overall look. The mouse has an ambidextrous design and uses the PixArt PMW 3360 optical sensor. The surface of the DM1 S2 is soft, and has a matte rubberized coating applied to increase the grip.
The main click buttons use Huano Blue micro switches, the exact model is the Huano blue with white dot. These have a life span of around 20 million clicks.
he scroll wheel has a rubberized coating on the middle part, with an arrow like pattern applied on the top. The sides are made from transparent plastic, to allow for the light of the LED to shine through.
The switch used for the middle scroll wheel click is a TTC white switch. The encoder of the scroll wheel is also made by TTC and is the white model.
Above the scroll wheel there is a small button which can cycle through all the preinstalled DPI and LED color profiles.
The left side of the DM1 S2 has two buttons, which have a glossy texture that creates a good contrast with the matte rubberized coating present on the rest of the mouse. The two buttons are used by default as the forward and backwards buttons. These buttons are using elevated switches manufactured by MWK.
The right side of the mouse is simple in design; its main purpose is only to provide a support for the fingers.
The back side is almost identical with that of the DM1 Pro S, here only the Dream Machine logo is present. The logo itself is illuminated by a single RGB LED, and the colors are used in tandem with the illumination of the scroll wheel.
The underside of the DM1 S2 is almost identical with that of the DM1 FPS model. The PixArt PMW 3360 optical sensor is placed on the middle of the base, and above it there is a label which has all the technical specifications of the mouse.
The DM1 S2 uses three Teflon made skates for the contact with the surface. These are placed in a triangle pattern, two at the back and one at the front.
The cable used on the mouse has a total length of 1.8meters and features a soft shoelace sleeving. The connection is done using a standard gold-plated USB 2.0 connector. In addition, the USB connector is protected by a plastic cap, which is unfortunately not attached in any way to the cable, so misplacing it will be easy.
