Logitech continues to expand the range of its gaming G-series in the direction of top solutions. Until recently, the flagship of the lineup was G502 Proteus Core, but in May 2016 it was replaced by the wireless mouse Logitech G900 Chaos Spectrum, which embodied all the best developments of the company’s engineers. Today it finally fell into our hands, and we can share our impressions of its use with readers.
The device box looks very solid. The design is dominated by a combination of blue and white fonts on a black background. The image and the name of the product is rendered on the front side of the cover, and the mention of its main advantages – on the rear.
Having removed the packing film and the outer cover, we see such a beautiful box with a laconic Logitech logo, which you will probably want to keep in your memory to add something of value there.
The delivery includes a mouse, a removable cable in the braid, a set of accessories in a black plastic box (receiver, extension cable, replaceable keys and plugs), instructions and information on the terms of warranty service.
Logitech G900 Chaos Spectrum looks like a futuristic mouse of a symmetrical shape. Aggressiveness to its appearance is given separately by the suspended panels of the main keys and the characteristic glossy insert between them. The coating here is a relatively smooth matte plastic with an average coefficient of adhesion. Traces of use accumulate on it quickly enough, however, it is cleaned as easily.
The design of the panels of the main buttons should be emphasized. They are made on the principle of a swing. Rear, hidden in the body, part of the lever is spring-loaded and provides an almost instantaneous reset of the button to its original position after pressing. Thanks to this, the LMC and PKM are very sensitive and responsive. Omron mechanical switches under them have a life-time resource for failure of 20 million activations.
The left button is triggered with a click of the middle volume, and the right one sounds very ringing. The middle button switch under the scroll wheel is tight, pressed muffled, with noticeable effort. The slopes of the scroll wheel to the sides are made easily and almost imperceptibly. At first I did not even notice that the wheel can be tilted at all, taking this movement for the natural backlash of the part. The scroll wheel has two modes of operation. In the inertial variant, it does not have a fixation and can rotate for a long time alone, providing a very fast page-flipping. In a fixed mode, each turn is perfectly tactile and distinguishable, accompanied by a characteristic informative crack with fast scrolling.
Switch modes by a separate mechanical key located just behind the wheel. Two miniature triangular buttons answer by default for changing the resolution. They are pressed easily, with a slight click.
All the edges of the mouse converge in front, forming a “predatory” beak. However, of interesting details, there is only a jack for connecting a USB cable.
Connected cord is located in the center and very low, although this moment is partially compensated by sufficiently rigid protection from inflection. In this mode, the mouse can be charged or used as a conventional wired manipulator. However, for the latter, it turns out that the cable fixing is not rigid enough, and it can slightly loosen the connector for a long time. Latches for more reliable fixing of a cord here it is not provided.
The USB signal cable has a length of slightly more than 1.8 meters, and is enclosed in a nylon sheath. It is quite thick in section, but, but very soft and flexible. The given form practically does not support and quickly straightens independently. On the side of the larger USB connector, a small ferrite ring is attached to the cord to eliminate signal interference. On the smaller connector, a similarity is made to a plastic plug, which in theory strengthens its grip on the mouse. In addition, the cord also has a comfortable adhesive tape, which makes it easy to adjust its length or fold it quickly for carrying.
Stylish plastic box with soft filler contains a set of replaceable magnetic keys for the right side of the mouse, a magnetic plug on the left side of the case, a USB extension cable and a miniature transmitter inserted into it.
By and large, an extension adapter is needed to connect the transmitter to it and place it closer to the manipulator, thereby improving the signal quality. And for charging it’s easiest to remove the adapter together with the transmitter and plug the released cable into the mouse. That’s where you start to think – why do you need these extra manipulations with small details? Was not it easier to make a regular charging docking station? After all, the mouse will still be used for the most part in wireless mode.
The left side of the mouse is made mainly of the same material as the top panel and only a blotch of even more tenacious opaque gray plastic is made in the front. The keys of the main buttons visually hang over the rest of the body in this perspective. Two side additional buttons are made of glossy plastic, their location is very comfortable and the thumb gropes them easily, thanks to the characteristic shape and the dividing strip in the middle. These keys are pressed easily with an “acute” click of the middle volume.
The caps of the keys stay on the magnets and are easily removed if they are pinched by their fingernails and pulled to the side. In place of the buttons, you can install one whole stub. This is done for those who do not need side buttons at all, or those who prefer to see them on the right side.
The right side of the mouse looks identical to the left side. Only instead of side buttons there is a stub.
The plug on the right side can easily be removed and replaced with two caps of side buttons, turning Logitech G900 Chaos Spectrum into a left-handed mouse.
The mouse feed has a regular rounded shape without sharp bends. Logo G is almost horizontal, at the very top of it. The bottom part, for some reason, is made of glossy gloss. Fortunately, she does not contact the palm of her hand.
Logitech G900 Chaos Spectrum has a symmetrical shape and is perfectly balanced for use with any type of grip, whether it’s “palm”, “claw” or “fingers”. The balance of weight along the axes is excellent, the body does not fall into either side. And the mouse itself is felt as light enough.
On the basis of the mouse there are four large Teflon legs in front, behind and on the sides. They have hooks for easy dismantling and replacement. Another two small legs in the form of arrows pasted near the window of the sensor. In addition, there is a power-off slider and a button for restoring the wireless connection. As the sensor in Logitech G900 Chaos Spectrum is installed infrared optics Pixart PMW3366DM-T2QU – one of the best, if not the best sensor in its class.
RGB-illuminated zones are only two – the G logo on the back of the mouse and the current resolution indicator in the form of three strips. The effects and color of these zones are adjusted synchronously.
Consider the software.
As for software, Logitech G900 Chaos Spectrum uses the universal driver Logitech Gaming Software version 8.91.48, the firmware version of the mouse – 1.2.20. The choice of interface language is available only once, when installing the program. The driver is registered at startup and is always active by default, although it can be disabled.
The basic screen of the driver shows which mouse buttons are active, the level of its charge and offers to choose the use of mouse memory or software settings.
The settings section of the sensor and key assignments can be integral or divided into two separate windows (depending on whether the mouse is based on the built-in memory or on the software). Here you can select the layout of the side buttons (All are active, all are off, the buttons are on the right or on the left). 11 keys are available for command reassignment. They can assign any mouse function, a standard combination of Windows buttons or a complex macro.
The macro is written in a separate window with minimal functionality – only keyboard commands are perceived, and delays can be edited between them. For the built-in memory, there are five profiles to choose from, in the case of using profiles from the driver, their number is unlimited. The resolution of the sensor is adjustable from 200 to 12000 dpi in steps of 50 dpi. You can configure five separate sensitivity levels, one of which is assigned to the “shift” function, that is, pressing this key activates this level. The choice is the polling frequency in 125, 250, 500 or 1000 Hz. Here you can include “increased accuracy of the pointer”, namely, – angular binding of the cursor.
In the backlight settings, you can choose which of the two backlight zones will be active (logo and resolution indicator), select the light effect (static, change colors or respiration mode), assign brightness and speed of the effect. The color palette allows you to select any of the existing colors for highlighting. In addition, the backlight settings can be synchronized with other company devices.
The battery screen visually displays in percent and hours how much charge remains in the battery and exactly where it is spent. Here, there is a quick adjustment of the backlight, because it is the main devourer of charge.
Calibration of the surface is responsible for setting the minimum detachment height (LOD) of the sensor. By default, two variants of surfaces from Logitech and some default setting are available. The user can add his own surface, and then follow the steps suggested by the program to calibrate the mouse sensor under it.
The built-in statistics module of clicks in the form of a heat map allows you to track which buttons are used most often, in how many and for how long. The function is curious, but useless in its essence.
To this software, you can bind a popular program for streamers – Overwolf. And in the tab in the form of a gear are the settings of the driver itself. Nothing particularly remarkable in them. The icon in the form of a question mark sends the user to the instruction for this driver, directly to the manufacturer’s website.
The test was performed on a Razer Goliathus WoT (Speed medium) mat. Logitech G900 Chaos Spectrum is the best ergonomic body wireless mouse of those that I had in my hands. The shape, weight and its distribution along the axes, the layout of the keys, the material are very close to the ideal, and this is no matter how hard the user holds this manipulator.
The same goes for the sensations of keystrokes and the use of the scroll wheel. The friction force of the legs is matched with a slope in the clutch. The mouse slides well, but has practically no inertia. In terms of autonomy, the mouse fully confirms the declared parameters. With the backlight off, it is able to work in a mode of very active use for more than 30 hours, without turning off in idle time. This should be enough for active players for two or three days, and for “office” operation (6-8 hours and shutdown when not in use), this period increases almost to a week. To fully charge the battery from the “dry” state, it takes exactly two hours of time in a normal USB 2.0 port. The mouse can be charged while working on the cable, and to change the wired and wireless mode it does not even need to be turned off. However, the lack of a convenient docking station for her is slightly frustrating. Backlight and software are made at a decent level, although in my subjective opinion, the LED logo might be less bright.
As already mentioned, one of the best optical sensors Pixart PMW3366 is installed here and it behaves just fine. First of all, it is worth noting that the difference or delay in the reaction rate of the mouse is not felt, regardless of whether it works on the wire or without it. Causing a cursor break is physically impossible, parasitic effects such as trajectory smoothing, drifting or linearity are absent, unless they are intentionally included. The tear-off height is set at the allowable minimum after the first calibration of the surface, and the sensor ceases to move at the slightest rise of the mouse. And most importantly, this behavior of the cursor remains in the entire possible range of resolutions, both at high values and at low resolutions.
Logitech G900 Chaos Spectrum is the world’s best wireless gaming mouse and sets the benchmark for all other competing solutions. In it everything is good: the sensor, the universal shape of the case, weight, switches, scroll wheel, the possibility of rearranging side keys, high autonomy and stability in wireless and wired modes, on-board memory and clear software, RGB-backlighting. It seems that when designing this device, the engineers of the company used the principle of the work of the ancient Greek sculptor Phidias and simply removed all unnecessary products from the product, leaving only necessary and worthy functions.
The only inconvenience that can spoil the pleasure of using Logitech G900 Chaos Spectrum in the long term is the lack of a docking station. The need to often connect the charging cable can subsequently lead to loosening and the output of the USB socket on the mouse out of order.
We hope that the absence of direct competitors will not lead to an excessive overestimation of the recommended cost of the Logitech G900 Chaos Spectrum in local stores, where it will soon be available for purchase.
