Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great for palm grip
The Logitech G400 gaming mouse was clearly designed specifically for palm grip.
Pro Thumb-rest
There is a built in ergonomic thumb rest so users can rest there thumb instead of constantly gripping.
Pro Comfortable side button placement
The two side buttons are located in an easy to reach, unobtrusive position.
Pro A true successor to the legendary MX518
The Logitech G400 gaming mouse is based off of MX518. It has a few minor incremental improvements that don't change what made the original so great.
Pro Accurate 3600 CPI optical sensor
The mouse has an accurate Avago ADNS-3095 optical 3600 CPI sensor. No angle snapping, no acceleration, no prediction.
Pro Quick-access CPI shift
Above and below the scroll-wheel there are buttons that allow increasing and decreasing between 400 and 3600 CPI on the fly.
Pro Good build quality
High quality rubberized coating is used among other materials to give a quality product feel.
Pro CPI shift
CPI can be changed from 400 CPI up to 3600 CPI without having to interrupt workflow.
Pro Reliable; keeps on going through the years
It will still work just as well as the day you bought it.
Pro Incredible flexibility
Many parts of the mouse are adjustable with interchangeable pinkie grips and palm rests to a custom weight system. The mouse is able to literally change its size and weight.
Pro Cordless version available
It also comes in a cordless version, called the RAT 9.
Cons
Con Scroll wheel is shallow and loose
Like the versions before it, the scroll wheel feels shallow and loose.
Con Lift off distance too high
The lift off distance is too high for this device but it can be fixed by using the tape trick.
Con Superseded by Logitech G400s
This unit is no longer in production though some units can still be found on Amazon and Ebay.
Con Laser (not optical) sensor
Laser sensors are just not that great when compared to optical sensors. Often there is acceleration issues with laser sensors.
Con Expensive for what the internal hardware is
Sadly the components inside of this mouse are pretty cheap, ranging from the switches to the laser sensor. For the price Mad Catz is charging one should expect higher quality components.
Con Forward / back buttons wear easily
The two buttons located on the side of the mouse (sometimes known as the page forward and page back buttons for internet browsers) wear out easily after only a few months of usage. That means that it requires extra force to register a button press, all while receiving no touch (or audible clicking) feedback. Frustrating but the mouse does continue working.
