Razor = no
I have a gamepad that's like 5 years old, and I'm in the minority here. It's not perfect, button 03 doesn't work all the time, and several keys stick, but the Razor keyboard I bought lasted 3 days, it's replacement was DOA, it's replacement's replacement lasted 12 hours, and the 4 mice I bought were... Well, let's just say, other than the gamepad, I don't own any other Razor gear anymore. I have a Corsair gaming mouse and Keyboard. I'm on my third mouse, and third keyboard. I still have a second KB and mouse.
I have a Corsair K65 keyboard, and M60 mouse (or something like that). The keyboard has red backlight and mechanical keys. The keys are MX Cherry Red, I wanted blue, but couldn't find them. >_> I like the red, though, so oh well. It was $100 for the keyboard, but it was very much worth it. The keyboard is aluminum chassis anodized black, and the backlight can be customized. I can push a button and only keys I want will have backlight, push it again and all keys have backlight. I can change the intensity of the backlight. There's a button to disable or enable the WIN key. The newer version of my keyboard is the RGB version, you can customize the backlight color, as well as intensity, specific keys, etc. The mouse is a lit mouse, with a matching black anodized aluminum chassis.
The first keyboard and mouse I got wore out. The second set, is also worn out, but still works. The mouse left click button works, but you gotta press kinda hard. I have the old set just in case something breaks.
The biggest downside to the keyboard is shorting out. If you spill anything on the keyboard, it WILL short out, and it will not work until it dries out completely. If you eat over your keyboard, don't get the Corsair with mechanical keys, or get a cover for it.
