The DM1 FPS mouse from Dream Machines is the first product we are reviewing that uses Huano switches for the left/right click buttons; these require a bit more force to actuate and offer a nice, tactile feel when used; this feature actually reduces accidental clicks and are rated for about 20 million clicks. In terms of the used optical PMW3389 sensor, which we have seen on many Razer mice before and we have not encountered any issues when tracking while playing games such as Wolfenstein: The New Colossus, Defiance 2050 or Mass Effect Andromeda. The overall comfort is enhanced thanks to the use of a really unique, flexible cable and low weight of just 83g.
