Cooler Master Storm QuickFire TK Blue Mechanical Gaming Keyboard


Well, it is finally summer. I have to say I have been waiting for quite some time now. Summer is one of the few seasons here in Vancouver where it does not rain just about every day, and that is a good thing. Too bad most of the time I am now stuck at...

great board


This was first mechanical board. The only thing I dont like is that I got a compact one and not full size. The lack of a independent delete key and arrows is more of a pain than I thought. Thats my issue not the key boards. So 5 stars, very nice board

price point feel keys feel good and light up well.

Amazing keyboard


Would recommend and buy another if the one I have were to hold up for another year or 2 at least.

Easy to type good for gaming, quick response time nice clacking noise, not too loud or quiet has adjustable red LED's perfect size

the key placement on numpad and the windows key lock takes time to get used to the force needed to push down a key also takes time getting used to (closest thing to a con)

Great keyboard


This is a medium size keyboard and some of the functions are not where I am use to finding them but this is just a mater of getting use to there location.

I bought this keyboard in 2013, and use it constantly. About a year ago, my cat jumped on my desk and knocked over a class full of tea, all over the keyboard. I took it apart wiped it out with paper towels. Set it in front of a fan, over night. The...

Very nice


This keyboard is awesome for gaming.. I've noticed I rarely use my ten keys so don't really miss them that much. If your looking for a good mechanical keyboard I don't believe you can do to much better for the money.

Very nice gaming keyboard. Buttons are fast to reset and activation is nothing, I've accidentally pushed keys several times. The lighting and schemes worked perfectly. The keyboard is good and heavy. This is a great keyboard

Wouldn't wana use it if you where doing spread sheets all day or need to cycle between the ten keys and the del button fast and arrow keys fast.

Clicking to glory


It's what you'd expect out of a mechanical keyboard. A bit of noise, high responsiveness, and it's a bit big.

Noise can be a bit of a downfall, but I don't mind it over the sound of how awesome it is.

Cooler Master SGK-4020-GKCR1-US


Great keyboard if you love red switches. Compact design is great if you are willing to adjust to it.

Drivers corrupt often in Windows 7 (evident when the keyboard does not turn on when the computer boots). Remove the driver and unplug/replug the keyboard fixes this problem. If you are using N Key rollover this will not work if you plan to configure...

great keyboard, nonstandard bottom row


this is a great keyboard, mine came with reds but i have two cm boards with blues and they are all top notch quality. the board is pretty heavy, which you should expect, and the numpad is pretty cool. very nice board if you don't plan on switching out...

there are two issues with this board. one is that the cable routing channels are pretty small, they fit a braided cable very snuggly, which is good, but it is too small for double braided cables. the biggest problem is that the bottom row has non...
