DESIGN & BUILD
The upper edge of the Lua is finished in a matte, black, soft-touch material. The edges, however, have a coarser finish to help ensure good grip and optimise handling. On the whole, this mouse has a plain and sober kind of look, but it doesn't scream cheapness. In fact, first impressions are really quite good.
Although the Lua is a pretty standard length (11.5 cm), it's still not long enough to support your wrist. The mouse's body is also quite slim (5.5 to 6.5 cm) so your ring and little fingers can't hitch a ride on the casing.
At 70 grammes, this mouse's weight does remove some element of "prestige" and it can make it feel rather hollow. However, it doesn't have any negative impact on use. The feet ensure smooth and discreet glide.
A symmetrical design means that the Lua is suitable for both left- and right-handed users. However, that in turn means that there are no buttons or controls on the sides of the mouse. In fact, the only extra button on offer here is located just behind the scroll wheel.
This button isn't particularly easy to reach, and so isn't practical for controls or macros that you need to use quickly and/or frequently. In its out-of-the-box configuration, Roccat uses this button for changing the dpi on the fly. There are seven levels to choose from in the driver (250, 500, 1000, 1250, 1500, 1750 and 2000 dpi), which is available to download from Roccat's website (see inset).
With a maximum polling rate of 1000 Hz, the Lua will be fine for day-to-day computer users (office computing, web browsing, etc.) and for those needing greater levels of precision (gamers, graphic designers, etc.).
A gaming mouse needs to track movements of at least three metres per second.
The Roccat Lua can track up to 3.5 m/s.
