Specs
Question 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 'Flickable' Scroll Wheel
Hitting a button behind the scroll wheel changes the scroll wheel from clicking up and down in a controlled manner to allowing you to flick it and quickly scroll through large portions of a document.
Pro Ergonomic design
The MX is an full-sized, ergonomically designed mouse that is designed to fit the hands of those who prefer a palm grip.
Pro Works on any surface
The MX uses "darkfield" technology to allow it to work on glass, mirrored surfaces etc.
Pro Good battery life
Once fully charged the mouse lasts for several weeks of moderate use before requiring further charge. Users are notified through lights on the mouse itself, and systray notifications when the mouse is nearing the end of its charge (generally several days before). Even after several years of use this appears to be the case.
The mouse uses one AA battery. A rechargeable NI-MH battery is included. The battery compartment is easily accessible, requiring no tools to assist.
Pro Well designed extra buttons
Three programmable buttons are easily accessed by your thumb.
In addition to the Zoom, Forward and Back buttons depicted, the thumb rest has a button for switching between applications, the mouse wheel may be held to allow drag navigation, and the mouse button may be tilted left or right for horizontal scrolling.
Pro Logitech Unifying Receiver (Dongle)
The [Logitech Unifying Receiver][1] allows you to connect multiple (up to 6) devices through one single, small dongle. The dongle itself is made up mostly of the USB connector, meaning it's small and so stays out of the way, and is unlikely to be bent or broken if knocked.
Pro Works whilst charging
Though the mouse works wirelessly, it's recharged via USB. When recharging, the mouse continues to work .
NB: The mouse still communicates wirelessly, so requires one USB for the Logitech Dongle, and one for the charge cable.
Pro Useful accessories
A travel case, a USB charge cord and a USB-to-outlet-power adapter, and a USB extension cord for the receiver.
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 Durability issues
A common problem are the buttons failing after only a few months of use.
Con Price
The price is currently hovering around the $70 mark, being marginally over this price from a number of outlets, putting it at the maximum limit of this question's price range.
Con Middle click not safe
When pressing the middle button by pressing down the scroll wheel, the left or right scroll-wheel buttons can be triggered. That can lead to accidentally going back in the browser or whatever is configured for these buttons.
The middle click should be a safe thing, where nothing else could happen.
Con No left handed version
Con Heavier than a typical mouse
At 147 g, compared to a typical weight of about 100 g, the mouse may take some getting used to. More often than not, heavier mice can tire your wrists after extended use without rest.
