Aside from turning the lighting on or off, you will only be able to control the lighting through the Razer Synapse or Open Razer Project software.

Sadly, the keyboard doesn't support on-board profiles or on-the-go profile switching. Overall, they keyboard is fairly easy to use: hold the function key to access the special keyboard controls that increase/decrease the lighting level, to record a macro, or to toggle 'gaming mode' (disables the Windows key). One huge reason I've dropped a couple stars from the score for this review: whether in Windows or Linux, you have no control over the speed of the various effects this seems like a huge oversight. (By default, the keyboard does a spectrum-shifting mode with the entire keyboard shifting colors at once and slowly over time cycling through the rainbow). (For example, I was able to put the keyboard into various modes, such as 'wave' and 'breathe', and was even then able to move the keyboard between devices while maintaining it's lighting settings. I'll note that while only Windows is officially supported, I have used the open source software that runs on Linux for the Chroma devices There are (unsurprisingly) fewer features, but it does provide some control over the keyboard lighting. They key size and spacing is nice, and there is just the right amount of RGB lighting peeking through (note that there are many, many levels of brightness so you should be able to find a happy lighting level with ease).

The tilt legs have two height levels to chose from, which is a nice perk at this level. The slip-pads are large (it looks like >one square inch for each of four). There is a bit of flex in the deck, but the overall build quality seems decent. The membrane keyboard is a bit stiff, and reasonably quiet (it's not silent, by any means, but neither is it 'clicky'). if I'd paid 50% more, then it might have landed at two-stars).
