Face on the Rival has a slight shape to it, favouring the right hand and is quite short at 38mm tall. This is to help with its versatility with various grip types.


The two side buttons are quite slender but have a tactile lip that sticks out so you can feel them without an issue. Underneath the buttons is a textured surface for extra grip.


At the back the SteelSeries logo dominates, giving it a large area for the LED lighting.


Unfortunately the Rival 100 is not ambidextrous and so does not feature extra buttons this side like with the Sensei, though there is extra textured grip.


Underneath there are 3 large pads for control and the sensor is positioned slightly off centre favouring the rear side.
