So I had this keyboard for about 6 months, and many LEDs went out, this is a problem across what seems to be almost all of these keyboards, so if you are buying this you should expect it, it is a shame as otherwise this is a really nice keyboard.

I'm very pleased with this keyboard. It weighs a fair amount and the build quality is fantastic, surpassing my expectations. I'm sure you could knock down walls with it should you choose!

No RGB lighting but I wanted something that would be in keeping with the Black/White theme so it serves the purpose intended really well.

Love the design. Backlighting is super bright on max setting. I have it at the lowest setting at all times. The Scroll Lock and Caps Lock keys don't glow unless turned on. They are not affected by user set lighting level. They glow at max brightness. The Print Screen key never glows unless you use it to lock the Windows Key. It also glows at max brightness. Would be nice if the lock keys would glow at set user level and only go full bright or pulse or something when used. Some of the bigger keys feel a bit cheap, took a star off for that. The keyboard is pretty heavy. Feels solid.

Got this for 80$. Can't beat it. Rubberized body, ABS keycaps with attractive font. Cherry switches, 5 dim settings and multiple illumination modes. No key rollover. 1000hz polling rate, braided cable. Isn't flashy like other "gaming" keyboards.

I love this board. Looks nice and simple, with the lights on AND off. LED lights are bright. All keys light up except for CAPSlock, Print Screen and the Scroll lock. It also has four light modes and an option to program what keys you want to keep lit, so that's pretty cool. Has a rubbery texture that feels really nice. It's pretty heavy but feels very sturdy.

Cherry MX Brown switches. This is my second QFR-i, after sending in the first for several dead LEDs. Unfortunately this replacement suffered a single dead LED. I've read Cooler Master has fixed this issue in current models, but it's still a bummer. Great keyboard otherwise, especially if you're looking for a TKL and like classic white LEDs.
