I have many peripherals from different brands.
Keyboards: Ducky, CM Storm, Cherry, SteelSeries
Mice: Logitech, Razer, SteelSeries, CM Storm
Mouse pad: Razer, SteelSeries, CM Storm
With Razer the only things I would ever consider from them are some mice and mouse pads. I'd never get their keyboards as I know there are different brands out there that offer way better quality for the price. I only like some of their mice, and surprisingly they're from the "entry-level" tier of their products....
