Delux is lining up significant upgrades for its top-of-the-line M800PRO model, which is a not too subtle clone of Razer's Viper series of symmetrical-shaped gaming mice. Enthusiasts have placed the M800's chassis as an intermediate between the full-sized Viper and Viper Mini, so it could be considered as a medium-sized equivalent. In order to match the competition in terms of specifications and features, Delux has sought to upgrade the M800PRO's internal hardware and has also made changes to its externals.

Pixart's PAW3395 has been selected as the new optical sensor, which is a significant generational upgrade over the previous M800PRO iteration's PAW3370. Delux has not confirmed, within its specifications list, whether MotionSync will be enabled by default. The upgraded sensor is capable of running this feature, and the vast majority of gaming mouse manufacturers have chosen to enable it. The PAW3395 is rated for a 26,000 maximum DPI, 650 IPS speed, 50 g acceleration and 1000 Hz polling rate. The lift off distance (LOD) is adjustable between heights of 1 and 2 mm.
