The Secretlab InfinitePrecision Armrest features a smooth height adjustment mechanism with a digital display indicating its precise height, designed for professional gamers. It is compatible with the Secretlab Titan Evo gaming chairs and replaces the standard armrests. The armrests can be adjusted in height from approximately 170mm to 245mm and allow for width adjustments and angle twisting. The package includes two armrests, mounting plates, bolts, hex-key wrenches, and batteries for the digital displays. However, practical issues include insufficient lowering for certain desks, forward-positioned mounting arms, and obscured displays when pads are adjusted inward. The build quality is robust, and adjustments feel precise, but the lack of a digital readout for chair height limits effectiveness.
