PerformanceThe Meduza HDST system performs alright, but it does come with a few downsides. Neither of the two sensors is centered, making the mouse feel a bit lopsided with only one of the sensors in use, and you will still have to get your head around some pretty noticeable angle snapping with both sensors enabled. The lift-off distance of the mouse is, although not quite up to a Avago ADNS-9500 or 9800 based mouse, still very good.
The mouse has three different modes of operation: optical, laser, and HDST. The mouse performs at its best with the HDST system that uses both sensors. The optical sensor on board does not perform that well and is, due to its position, odd to game with. The laser sensor offers some adjustments that are not available to the mouse in HDST mode. You can, for instance, turn the angle snapping down to a minimum. You cannot, however, turn it off completely. With only the laser turned on, the mouse handles itself a bit like one of the old Microsoft laser mice with the sensor placed off-center to one side of the mouse.
A sensor, placed along the center-line of the mouse, makes the mouse feel much better while gaming. You still get some remnants from the odd positioned sensors in HDST mode.
The Meduza might be for fans of the now ancient Logitech MX 518. The angle snapping is, however, a tad bit more invasive on the Meduza. Tracking performance is pretty stable on all types of surfaces which is great, but almost any high-end laser mouse out there can do the same. We do like the generously large and high-quality Teflon mouse feet the Meduza is equipped with; they work well with both hard and soft mouse mats.
