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...

Really nice


Nice, simple, small keyboard with all keys available at the press of a button. I personally bought this piece of work for a game called osu!. Results were amazing, you should definitely buy this keyboard if you're a gamer

No cons

Mine came with one LED burned out which I was not happy with. Newegg did offer to replace it but I'm afraid another will come back in worse shape based on the reviews I've read about CM keyboards. I liek how it feels and looks so 1 LED is not a huge...

Feels great! Looks great

One LED does not work

Overall good keyboard


Overall, I'd give it a 4/5 rating because of the weird layout configuration. I regret getting this over just a normal tenkeyless design. I also thought that it would have came with white backlighting, but it turns out that the switch type determines...

Cherry MX Blues ; Backlighting is VERY BRIGHT ; Compact ; Windows Key Lock ; DETACHABLE (BRAIDED) CABLE ; Solid build quality, doesn't flex much at all

The numpad/arrow key layout is very hard to get used to. I've owned this for a month now and with daily use am still getting confused on how to use it sometimes due to the fact that it can be tough to distinguish when backlighting is on ; The NUMLOCK,...

Had To RMA


If did not have to RMA the product due to the 2 errors then it would be a five star product. I normally do not review a product after only 3 hours of use. But from what i have experienced. It is a vary nice, Small, Clicky and sexy product. It is worth...

Well made construction ; Well lite back light with option to change brightness ; Nice small gives space on desk ; Sexy sounding clicky cherry mx blues

Had to RMA due to the "A" key not clicking or having a tactical feel ; On the num pad the 2 key's LED was placed upside down witch made it so you cant see the led light illuminate it

Great mechanical keyboard


Very solid mechanical keyboard ; Has survived several liquid spills . (when dried) ; I even spilled juice on part of the switches which gunked them up . This was easily fixed by putting drops of iso alchol into the switch mechanism and then clicking...

the red lights are worthless

A solid mechanical keyboard.

Keys feel nice, keyboard is compact and has nice features. Lighting options are good

It's a little less comfortable to use than some other keyboards

Cooler Master SGK-4020-GKCL1-US


Bought another with quiet MX Brown switches last year... that's better for nighttime & conference calls. Blue is nice and crisp, pretty similar to my ancient Northgate Omnikey. I like both.

Crisp, compact, solid. Backlit. No other frills, no problems ; The combined arrows/numpad hasn't been a problem for me, even in spreadsheets (I just use enter/tab/mouse to move.)

Getting into BIOS setup can be tricky if you have to turn off Numlock and hit Delete in a 1-second window, so keep a regular keyboard around and/or disable Numlock at boot in BIOS
