Top but...
The keyboard is top-notch. Its elegant, modern design and customisable backlighting make it a real asset to any gaming or office configuration.
However, there are a few negative points to note. Firstly, the lighting choice is not persistent. This means that when you completely switch off your PC and then switch it back on, the keyboard doesn't remember your previous lighting settings. You have to reconfigure the lighting effects every time you restart your computer. So if you're like me and you like the 'breathing' effect, you'll have to reactivate it each time. It's quick and easy, but in the long run it's frustrating.
Secondly, although the keyboard isn't particularly bulky, it is a little heavy. This extra weight can be felt if you need to move your keyboard regularly or if you have a mobile office. For some users this can be a disadvantage, especially if portability is a priority.
