The standard lift off distance on a cloth mouse pad is 1.5-1.8mm though it will be a bit higher when using a plastic pad being 2.2 - 2.4mm. To enable the plastic pad setting a certain button combination has to be pressed on the gaming mouse itself.
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 A low lift-off-distance of about 1.5-1.8mm
The standard lift off distance on a cloth mouse pad is 1.5-1.8mm though it will be a bit higher when using a plastic pad being 2.2 - 2.4mm. To enable the plastic pad setting a certain button combination has to be pressed on the gaming mouse itself.
Pro Excellent 3200 CPI optical sensor
The Zowie FK1 gaming mouse uses an Avago 3310 optical sensor which is regarded as one of the best in the world. It has no built-in acceleration and no angle snapping. It’s practically jitter-less when set at 125 and 500Hz polling rate, and has barely noticeable jitter at 1000Hz.
The Avago 3310 has no native CPI, it is made to have each step of 50 CPI work as well as the previous one. With CPI steps of 400/800/1600/3200 for the FK1, all CPI choices should work equally well.
Pro Can be used by both righties and lefties
The Zowie FK1 gaming mouse uses an ambidextrous design with a wide base for the palm rest.
Pro Comfortable for most grip types
FK1 has a very universal shape and size, making it a safe choice for most people regardless of grip type and hand size. Except for people with large hands who use the palm grip, who may need a larger model of the mouse.
Pro No unnecessary functionality
Zowie has kept the mouse remarkably simple. There's no RGB lighting, adjustable weights, or superfluous buttons that end up only getting in the way. It's plug-and-play and requires no additional software. You can customize only the essential settings such as lift off distance, polling rate, or switch between left or right-handed modes with just a combination of specific button presses.
Pro Ships with a set of replacement feet
The Zowie gaming mouse has an extra pair of mouse feet in the box so users can replace their old ones when the time comes.
Pro Switches have a bit harder press so you don't accidentally kill your teammates
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 Two of the side buttons are unutilized in normal use
While the mouse has four side buttons, only two of them can be used at a time, depending on which hand you are using it with.
Con A bigger model might be needed for large handed people who prefer a palm grip
Due to its short height and the small hump on top of the mouse, it might not be suitable for people with large hands who prefer using a palm grip.
Con Slight lens rattle
There is some lens rattle when you pick up the device and shake it.

Con Only 4 DPI settings
Even though the ADNS-3310 sensor supports DPI settings in increments of 50, the FK1 only lets you choose between 400 / 800 / 1600 / 3200 DPI.
Con Not quite as comfortable as a non-ambidextrous mouse
Due to its thoroughly ambidextrous design, sometimes the ring and pinky fingers can touch the side buttons. Even though they are deactivated and won’t cause mispresses, they are still not as comfortable as non-ambidextrous designs.
Con DPI switch can't be used on-the-fly
A DPI switch is available, but it's located under the mouse, so it can't be used on-the-fly.
Con Pressing the main buttons may feel tiring after some time
Though it’s usually a matter of preference, the main buttons are a bit harder to press compared to other mice, which some people may find tiring after long periods of use.
Con Cord can break easily
The cheap rubber cord might be prone to breaking easily.
