Cyborg’s RAT series of mice is particularly distinctive series of mice with multiple adjustable moving parts.  The Rat 7 has an adjustable weight, thumbrest, palmrest and pinkie rest.

Depending on the exact version of the Rat 7 the palm rest and the pinkie rest are replaceable.  The 3 palm rests have one featuring the same soft-touch finish as found on the body of the R.A.T. one with a rubber inlay and one that is 4mm thicker to increase the height of the R.A.T.  The 3 pinkie grips have one featuring the same soft-touch finish as found on the body of the R.A.T. one with a rubber inlay for enhanced grip.and onene that offers a ‘wing shaped’ design, allowing you to rest your pinkie finger during play for increased grip.

The Mouse is available in multiple colours including black, black and red, red and white and is coated with a soft rubberised coat that does feel nice and grippy.

Features and Accessibility

Design & Visual Accessibility

The RAT series of mice has a unique look that will either appeal to you or you will not find aesthetically pleasing – very few people are neutral about its look.    As a consequence of the fact that every part of the mouse is adjustable in some way the sections are all disconnected from each other giving it an oddly kit built design.

Audio & Accessibility

The RAT has no audio element.  It has no speakers built in to the mouse itself and the software has no audio element such as notifications.

Input and Touch

This mouse is customisable to most hands.   It is however relatively large even in its most compact setup and hence will not work well for those with small hands – medium or larger.

The standard model is covered in a rubberised grippy surface that actually is grippy and resists sweat quite well.  This grippy material is also wrapped around the main scroll wheel and covers the two main buttons entirely. The smaller buttons are made from a smooth clear plastic and the secondary scroll wheel is a grooved metal.

The weight is customisable but even at its lowest weight is still relatively heavy when compared to a normal consumer mouse.

It feels extremely durable and it has a metal frame and base that reinforce this solidity.

Ease of Use

The strength of the RAT series of mice is its ability to be customised both in the number and use of buttons and its physical shape.  This unavoidably means that it takes time to setup and adjust and time to get used to the number of buttons.  I found myself adjusting its shape regularly for a couple of weeks until I got the the right shape for me.  The fact that an Allen key is part of the design has helped here – you always have the ability to make these adjustments easily.

I am also still not using it to its full in terms of the buttons – some of them are specialised to FPS games which is not something that I am using it for.  The software and drivers are about as good as you would expect for this sort of peripheral but not as good as they could be.  They provide good functionality but are not as intuitive as they could be and are not that accessible, for example they use black text on a grey background.

The mouse can hold three profiles at once and the Cyborg site has a number of profiles available for download covering most games and many programs.  For example I have a Windows 8 layout on the first mode that lets me share and interact with the charms menu; the second mode has Chrome commands on that let me go forward and back, switch tabs and clip webpages and the third mode has whichever game I’m playing at the moment on.

The fact that the mouse is so customised for my use also has the unfortunate side effect that everyone else who has tried to use it has had problems – this is not one for sharing.

The Cyborg R.A.T. 7  is a highly customisable mouse that will appeal to a subset of people who enjoy tinkering and spending time to get their setup exactly as they want it.  It has some utility as an accessibility aid, particularly to those who needs a high DPI mouse of a specific shape.  The mouse’s looks will put a number of possible users off as will its size but if those are not issues for you then this is a solid choice of mouse.
