A good optical sensor is good. But two sensors, is it even better? This is the question we can ask ourselves when discovering the SteelSeries Rival 600. This gaming mouse uses a second sensor dedicated exclusively to the measurement of the depth, for an even more pointed detection of the lifting distance. What's better than the competition?
Like the Rival 310, the Rival 600 is intended for right-handed only because of its asymmetrical shape, inclined to the right to better fit the curves of the hand. The result for the right-handed grip very comfortable, provided that we do not have a hand too short, because the mouse is quite long (131 x 69 x 43 mm). It remains nevertheless fine. Its proportions are finally halfway between those of the Logitech G502 (132 x 75 x 40 mm) and the Logitech G403 (124 x 68 x 43 mm).
From left to right and from top to bottom: mouse alone; palm grip, claw grip, fingertip grip.
Size of the hand: about 20 x 10 cm.
The grip is enhanced by silicone inserts on the edges, soft to the touch but also completely smooth, so less slip resistant than those used on the Rival 310 and Sensei 310. If this is not a problem on the left side, because it is slightly concave, it is more embarrassing on the right one is conversely slightly convex. Immediate consequence: the fingers slide a little if you release too much pressure. This is not necessarily very embarrassing in a nervous game where the intensity of the action is naturally tighten the mouse firmly enough, but it is more boring for the quieter uses, if one needs to frequently raise his mouse to refocus on the carpet (multi-screen configuration, use in low sensitivity …).
Fortunately, the fluidity of movement of the Rival 600 is very good thanks to its lightness. With only 97 g on our scales (96 g announced and 103 g if you measure with cable plugged – it is removable – and placed next), the mouse glide with agility on the carpet, helped by its 3 pads PTFE. SteelSeries has nevertheless thought of players who prefer heavier mice and offers an adjustment system based on 8 small masses of 4 g each, to be inserted under the slices of the mouse. Rather well thought out, it also makes it possible to modify the equilibrium of the Rival 600. The setting up of the small masses could have been easier, but once its preferences found, one should in principle not retouch there.
Small 4 g weights are delivered in a rubber storage case. The slices are held firmly by magnets.
Regarding the buttons, we appreciate the concave shape of the two main that improves the maintenance of the fingers in a good position by preventing them including sliding outward. Without achieving the excellence of the latest Logitech mice in the field, clicks are quite responsive and offer a satisfactory consistency. However, the click quality of the right button is slightly lower than that of the left, giving a slightly lower impression of responsiveness. Click noise is quite discreet.
Side slice buttons, we appreciate their good positioning: they are close to the thumb without being too prominent not to incur unwanted activations. Their release is pretty straightforward. In addition to the two buttons now usual, we find a third positioned in front of the thumb. It is unfortunately not easy to reach, unless you have a very long thumb, making it difficult to use in the heat of the action. It will therefore rather be assigned a function of lesser importance, which is unfortunate since such a button may, on some mice, be used to lower the sensitivity of the sensor on the fly when it is held down to increase accuracy (hence its name "sniper" button). This role can nevertheless be played by the last button located above the wheel, which allows to switch from one sensor sensitivity level to the other (default function). Since the mouse only manages 2 sensitivity settings at a time, you can easily rely on this button for such a function, especially since it is possible to operate it with the middle finger without too much difficulty.
The wheel, for its part, is pretty well notched while remaining quite soft. It can not be tilted laterally (for horizontal scrolling or to add two other functions, for example). Some words finally on the backlight. Very neat, it can vary with a nice fluidity according to several effects configurable in the software of the mouse. 8 areas are illuminated: wheel, logo, and 2 bands on the top of the mouse each subdivided into 3 zones (one LED per zone). Synchronization is possible with other branded devices and some games and applications (including Discord) support backlighting directly.
The Rival 600 uses the TrueMove3 sensor, manufactured by PixArt and already used in the Rival 310 and Sensei 310. An excellent optical sensor, able to withstand accelerations up to 50 g and operate at speeds up to 8.9 m / s. It's impossible to make him win: the quickest movements are perfectly managed, and always with excellent precision. This sensor also allows a 1: 1 optical tracking of a range of 100 to 3500 dpi, for a faithful capture without acceleration. SteelSeries also recommends choosing sensitivities in this slightly smaller range to maximize accuracy. If 3,500 dpi is already enough for most players, including those who enjoy playing in high sensitivity, TrueMove3 can everything goes up to 12,000 dpi, far more than you need, even for multi-monitor Ultra HD configurations. Remember that at 12,000 dpi, a movement of less than one centimeter is enough to cover the full width of an Ultra HD display: goodbye accuracy in these conditions – we appreciate that SteelSeries itself explains that the sensitivity It does not have anything to do with accuracy. Although it actually has a TrueMove3 sensor, SteelSeries adds the suffix "+" to its name to mark the presence of a second optical sensor. The latter is only used to measure the lift height of the mouse, for higher measurement accuracy. Thanks to this second sensor, there is no need to raise the mouse very high, since the lift-off height is here extremely low: it can be adjusted up to 0.5 mm. So just a tiny uprising to stop the movement of the mouse pointer. One gains in speed of execution and in comfort if one has the habit of frequently refocusing one's mouse on the carpet (game in low sensitivity, especially). Nevertheless, note that such a capacity will not be useful to all, because many players are comfortable with a higher cutoff height (between 1.5 and 2 mm, for example).
The two sensors (TrueMove3 +) of the Rival 600.
Caution when setting this detection height also, since a level that is too low prevents the mouse from working on certain surfaces. As a precaution, it will be better then to increase the cutoff height before using your mouse on another coating, or to have a second mouse on hand. The height can then be reduced again without any problem, as the sensor adapts automatically to the surface – it is simply the transition from one surface to another that can be problematic when the lift-off setting is low.
