This keyboard is amazing in so many ways. It's performance is impeccable and the build and LED quality is top notch. I switched this out from my K558 Rainbow keyboard because I wanted to try out a Full RGB one and needed more space on my desk. This keyboard was a perfect choice.
Typing on it is very satisfying and responsive. Also, I am using it without a palm rest of any sort and it is still very comfortable to type on. This keyboard clearly doesn't come with a palm rest as it is part of the design.
The RGB lighting itself is also amazing. There is no software needed to use it either. It is all ready to go out of box with about 18 different color effect modes along with stationary colors. The lighting has no on/off feature, but it can be 'disabled' by just turning down the brightness till they are off which is good anyways since it just saves an unnecessary separate command for doing that. The animations are extremely smooth and satisfying and the RGB appears to have a full range of colors (although for solid colors, you are limited to 8 since there is no fine tuning software). You can also change the speed of animations using Fn+'- or +' keys and you change the direction of certain animations using Fn+'left arrow'. The color modes are changed using Fn+'Ins, Home, PgUp, Del, End, PgDn'. Each one has 3 different modes.
Aesthetically, this keyboard is awesome too. It's nothing super flashy. The brushed metal is a lot more darker in person. It is noticeable, just not silver or dark gray, but closer to a black brushed metal, which I personally like a lot more anyways. The coolest thing I like about the build itself is that there is no red plastic on the keyboard anywhere. This means that anyone can use this keyboard regardless of the work station or gaming build color scheme. This is a huge plus to a lot of people who want to use the awesome products Redragon makes but choose not to because of the forced red hard plastic that is found on many other models.
Now with every product, there is always some sort of flaw, with this keyboard, I found that there is no way to custom map which keys stay lit. Unlike my K558 where I can select individual keys to stay on and quickly swap between setups for different games, this keyboard only allows animations or solid colors across the full board. Being able to do something like set up my WASD to light up one color and have my number keys be a different color would have been nice, but it is a feature I won't use anyways since that would defeat the purpose of having a full RGB keyboard.
My final verdict is that this keyboard is an absolute steal. The price is very fair and affordable and the build and lighting quality is extremely impressive. It will fit any build design and looks beautiful as is. Plus the mechanical keys are just so fun to type on. If you need a new keyboard, this is the one you should get.
