Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Comfortable to use
Its rather small size and lower than usual height allow for a substantially comfortable grip. The sides have a dent which helps fingers positioning. Additionally, the sides are smoothly textured so you shouldn’t ever feel like your hand is losing its grip.
Pro Well suited for fingertip and claw grips
Unless you have small hands, this is a mouse that is meant for people who use either the claw or fingertip grip. In addition to being a small mouse and having low height, it's also extremely light, weighing only 68 grams. This makes it easy to control with a fingertip and claw grip as it relies on the mouse being as agile as it can be.
Pro Well built
Even though it’s a budget mouse, it has high quality components to ensure that the mouse can last for years. There are no unnecessary moving parts while button clicks are clear and don’t give out after heavy use. The body of the mouse consists of rubberized coating at the top and textured plastic on the sides which gives it a quality feel.
Pro Good amount of customization provided by the accompanying software
The software is very simple and easy to use. It lets you change the DPI steps, double click speed, vertical scroll speed, polling rate, very basic lighting control and the choice of hand-mode. In addition, it has the option to reassign its buttons, but since the Lua has only four buttons it’s practically useless as the main three are almost always invariable.
Pro Excellent budget sensor
The Avago A3050 optical sensor that the Lua uses has small, unnoticeable prediction and doesn’t carry over perfect tracking at high speeds (depending on the chosen DPI setting, over 60-120 inches per second or 1.5 m/s-3 m/s). But unless you use it at extremely low sensitivity, it shouldn’t be a problem. When reaching such speeds, some negative acceleration may be noticed.
Pro Full Linux support
Roccat has good Linux drivers.
Pro Can be used by both righties and lefties
Uses an ambidextrous design that actually feels as if it is and ergonomic design no matter what hand is using it.
Pro On-the-fly CPI switch
There is a button right behind the scroll wheel that will allow for on-the-fly CPI switching.
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 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 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 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 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 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 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 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 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.
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 Long, quality wire
To charge the mouse, plug it into the included 6ft braided cable.
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 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 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 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.
Cons
Con Lacks sidebuttons
Since it’s in the style of a classic three-button mouse, the lack of side buttons limits customization options.
Con Small size takes some getting used to
The Roccat Lua is a small mouse, measuring only 11.5 cm in length and 3 cm in height. The width is pretty standard with 6.5 cm at the back and narrows down towards the front. The small size might raise some concern about the grip. If it’s your first mouse of this size you might need to adjust your grip to accommodate for the smaller scale of the mouse. Commonly the grips change and include some elements of a fingertip grip.
Con Top DPI value may feel insufficient for some gamers
The DPI amount caps at 2000, which might not be enough for some.
Con Can suffer from small amounts of jitter on high DPI values
This mouse's DPI setting can be set from 250 to 2000, in increments of 250. At DPI settings higher than 1250, it can generate small amounts of jitter. The mouse works the best at 500 DPI with a 1000Hz polling rate.
Con Rubber cord is prone to breaking
It has a rubber type cable which means there’s less resistance and drag against the desk but at the same time can be more prone to damage when bent.
Con Light weight takes some getting used to
At 68 grams, it's about 30% lighter than most mice. Switching from an average mouse might take some getting used to and feel like the Lua is a bit floatey.
Con Uses an outdated sensor
The Lua’s optical sensor might be a bit dated, since it was released five years ago. Still, it mostly only shows weakness when it is facing really fast mouse movements. And as long as you are aware of it, this shortcoming can be entirely avoided.
Con Low palmrest height
The low palmrest height may be a turn off for some palm style users.
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.
Con Expensive
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.
