I wasn't sure what to expect with this keyboard, given the price. "DIERYA" is not a brand I'm familiar with, but that could entirely be attributed to my own ignorance. Regardless, this keyboard was a pleasant surprise. The material is quality PBT, and the keys all feel solid, as do each of the switches. The frame is made of the same material, and they keyboard has some deceptive heft to it, given the size.
The lighting options on the keyboard are numerous, as are the available colors. The software is fairly easy to understand, and the keyboard has built-in macros to quickly switch between modes, colors, speed, and brightness. The keyboard also features FN macros for screen brightness, volume, media control, and a WIN key lock, and SPACE lock.
Another great thing about this keyboard is the ease at which both the keys and switches are changed. Both are very simple "plug and play" installation, which makes experimenting and customizing a breeze. Packaged with the keyboard were the needed tools for both, and a quality braided USB cord with a 90 degree angle. Overall, this keyboard has many pleasant considerations from the manufacturer, and I would recommend it to anyone.
