As the Firefly is powered via USB you will need to make sure you have enough spare on your PC or MAC. Out the box it defaults to the spectrum mode, but once the software has been installed, swaping the lighting effect is easy to do. The colours are noticeable during the day, vivid and vibrant in the dark.



The USB connector is gold plated and has a 2.1M/7ft braided cable which is soft and easy to manage. As mentioned earlier there is no included wrist rest which is a shame as, for this price, there could have been some cushioning included within the layout itself. In use there was no real problem with comfort unless you rested your palm on the rim though this shouldn't really happen without intention as the generous size (355 x 255 mm) of the Firefly can easily accomodate large hand motions without a problem. The materials used are tough and durable and is easy to clean. As to whether it is actually 'waterproof' or not, there is no statement on this but it is unlikely that a moderate coffee spill will cause any major damage.

The surface itself tracked well using the Razer Mamba, Razer NAGA EPIC Chroma, as well as the SteelSeries XAI and a Corsair Gaming M65. Mice literally glide across the surface with an almost air hockey feel, yet didn't feel 'slippery' in a way which couldn't be controlled. In games and raves, the Firefly was a surprising treat and it becomes easy to imagine the potential of how the lighting effects could be used by developers to create that extra sensory experience in games.
