Pros
Pro CPI for your preference
You can adjust the mouse from 240 to 4000 CPI, in steps of 80. You can also change the CPI on-the-fly, which comes in handy when playing FPS games.
Pro Great at high speeds
The G402, unlike many other mice, won't spaz out if you move the mouse faster than the sensor can pick up the readings. The sensor has a max read speed of about 2.7 m/s, but the G402 uses an accelerometer and a gyroscope that will help fill in the missing data in case you outpace the sensor. That should eliminate any worry of judder or other tracking issues ruining your game. It's a great feature if you're a low-sensitivity gamer and sometimes move the mouse really quickly.
Pro High build quality
The mouse is well built and durable - what one would expect from Logitech.
Pro Crisp and light buttons
G402 has 8 programmable buttons. The buttons are separated from the shell and give you an enjoyable clicking feel. The scrolling wheel is light and small. Overall, the buttons feel nice and crisp.
Pro Low lift-off distance
The lift-off distance is less than 2mm. The mouse stops tracking the moment you lift it off the table even a little bit.
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.
Cons
Con Doesn't have a very premium look
The design for the G402 is not very inviting. The mix between matte and glossy black plastic is a bit incoherent and it's missing some premium materials. Even the cable is nothing fancy, it's just a plain black rubber cable.
Con You get full feature support on Windows only
Logitech supports Windows only, both with drivers and software. While this mouse can be used with macOS or Linux, you won't be able to customize it since it's missing the official software for those platforms.
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.
