Forget what you know about wireless mice - the Logitech G900 Chaos Spectrum gaming mouse is a wireless mouse that not only matches wired mice, but also sometimes surpasses them in terms of responsiveness, with Logitech claiming 1ms report rate (that claim needs to be tested still).
Ranked in these QuestionsQuestion Ranking
Pro Just as reliable as a wired mouse
The G900’s transmitter performs well enough that it’s almost indistinguishable from other wired mice, in some cases even surpassing them in click latency tests. This, combined with its high quality sensor, makes it a great wireless option for a gaming mouse.
Pro Extensive customization
Aside from sensor and DPI adjustments, the G900 features extensive customization options. It has plenty of extra buttons that you can rebind with commands or macros. The scroll wheel can be changed to either free-rolling or notched scrolling. You can also choose to use it as a wired mouse, if you prefer. Full RGB lighting support lets you customize its look to suit your gaming rig.
Pro Excellent sensor
The Logitech G900 uses a PMW 3366, a virtually flawless sensor that doesn’t alter movement in any way. It is seen as a slight upgrade to the FK1’s sensor but the differences are so minor that any improvement is only marginal.
Pro Great scroll wheel
The metallic scroll wheel can be switched between free scrolling and click scrolling through the button right in front of it. You can also tilt the scroll wheel either way, and program them to a specific task.
Pro On-board memory profiles
You can save your custom button bindings right on the mouse so that no matter which computer you use it with, your profiles are there.
Pro Long, quality wire
To charge the mouse, plug it into the included 6ft braided cable.
Pro Can be used comfortably by both righties and lefties
The side buttons are removable, so even if you are left handed you can comfortably use this mouse.
Pro Can be used as a wired mouse
You can still use it as you would any other wired mouse if you wish while it's charging, or you could use it as a wired mouse all the time if you prefer.
Pro Suitable for all grip types
This mouse is rather flat, without any big humps ensuring that all grip types are welcome, as long as your hands are the right size.
Pro LGS companion software conveniently facilitates tweaking
Option tweaking is done via the Logitech Gaming Software (LGS). This includes sensor related options, the choice of side buttons, button remapping, macro creation and thorough lighting control. All of this is connected to the five available profiles. The LGS is available on Windows and Mac systems.
Pro Sensor customization
The options for sensor customization include changing of polling rate and DPI steps. There are a lot of choices because the DPI steps range from 200 to 12,000 with steps of 50.
Pro Button clicking gives a satisfying feel
The main left and right buttons are built in an uncommon way, mainly to provide a more satisfying feel when they are clicked. Each uses a pivot bar to provide consistent clicking, regardless of where you press the button. In addition, there are metal springs under the main buttons for faster recovery after clicks.
Pro Lasting and sturdy build quality
Logitech mice typically have above average build quality and the G900 is no exception. The body is made with a rubberized coating that doesn’t scratch easily and is pleasant to hold. The main buttons have a mechanical pivot design that contributes to its precise and tactile button clicks. The cable is braided, which prevents it from twisting and damaging the wires.
Pro Convenient charging
The battery lasts between 24 to 32 hours, which is quite reasonable especially since charging it is easy. Simply connect its wire to the mouse and it will fully charge over the course of two hours, during which the mouse is usable.
Pro Light mouse for easy movement and control
Weighing 107 grams, this mouse is quite light for a wireless mouse. This is uncommon because the battery usually adds a lot of weight. A lighter mouse is useful since it’s easier to move and control.
Pro Flawless wireless connection
Some wireless gadgets may become unreliable at times due to interference from high Wi-FI and Bluetooth traffic. Despite this, the G900 is superb at keeping its wireless connection flawless.
Pro A bundled receiver adapter allows you to improve the connection strength
You can also attach an included receiver adapter to the wire and dangle it close to the mouse to further improve reception.
Con Limited thumb buttons
Those switching from the G700 will find that they are going from 4 thumb buttons to two. Yes, the G900 allows for customizable side buttons of up to 2 on each side, but those who like to have more than 2 thumb buttons for gaming (especially MMOs) may find this hard to adapt to.
Packed full with features, it’s no surprise that it bears an expensive price tag of $150. Spending that much money on a mouse might seem impractical, but you certainly get what you pay for.
Con Scroll wheel can rattle lightly
It is not uncommon that the scroll wheel can lightly rattle while on free-scrolling mode.
