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...

Cooler Master SGK-4020-GKCL1-US


This is the first mechanical keyboard I have owned. I did the research on the known cons beforehand, so I knew what I was getting. I have been very satisfied with this keyboard for gaming and for school work.

Frame feels sturdy ; Compact design allows it to be carried around and fit on small desks ; Typing feels good, quality switches ; Good looking design, goes well with most other black coating + blue LED products ; Easy to disassemble and clean with the...

Compact numpad + arrow set can be annoying for some applications ; The lighting modes seem pretty useless without any way to customize well (but I think that might be asking a bit much for the price range)

Don't Buy This Keyboard


Cooler Master does not cross-ship, therefore you had better have a backup. YOU pay the postage to return it, so at $20.00 a pop to return it. Doesn't take long before you've paid as much to return your keyboard as it does to replace it. Save yourself...


Very low reliability. I bought the previous model of this keyboard and I'm on my second RMA in 8 months. Both just stopped working while I was typing on them. Lights go off, and it's dead

I won't list any pros and cons because the only other mechanical keyboards I've even touched are a really old razer model and the same keyboard but with red switches instead so i'm no expert but this keyboard is awesome I'm only writing a review...


None so far

everything is good


looks cool, easy to type, everything i wanted in a blue mechanical keyboard

thought i could pick what keys i wanted to light up, not a big deal though

Awesome keyboard


I didn't buy this here but thought I'd leave a review since I shop with Newegg quite often. I installed O-rings as soon as I received mine and typing is a pleasure. Everyone says cherry mx blues are extremely loud but I don't find it much louder than...

Cherry mx blues, nice even backlighting, solid build quality, braided usb cable, a joy to type on

Metallic pinging noise on a couple of keys (thankfully only in the top row on # keys so far) ; Wish the F12 and FN key LEDS could be adjusted in brightness as the only options are full brightness or off, which looks odd when you have the rest on a...

Not a Single Negative For Me


Biggest thing here, my unit came with a faulty cable. I noticed bad connections and I tried with multiple cords. Turned out the gold plated cable I got had a malformed pin-out on the mini USB side, there was an extra sliver of metal embedded in the...

More of a thumbs up to Cherry, but the switches are amazing. LEDs are super vibrant or can be turned down. Size can be a negative but it fits my desk perfectly, full sized would not fit on my keyboard tray. Cooler Master's choice to make the underlay...

Nowhere near a deal breaker, just nitpicking. Would have liked the option to light all keys rather than in "zones" ie num lock has to be off for arrow key lights to be on, and vice-versa if I want to use arrow keys the light will always be on witch...

I ended up modding the keyboard by removing each key and placing an o-ring on the bottom, (there are tutorials on Youtube of this) and it's significantly nicer feeling to type on and sounds slightly quieter.

Nice narrow keyboard - no more bumping into the numpad keys with the mouse. Very nice looking blue led keys, several led modes, very durable feeling, nice braided detachable cord. Fits excellent in a desk with a wrist/hand rest already on the pull out...

Very loud and clacky sounding/feeling, kind of feels like typing on a typewriter- that's just the cherry MX blue switch though I presume. It's also very thick, the top of the keys to the bottom of the keyboard is about 1 inch - not very comfortable...

Very bad customer service!


I will never endorse any Cooler Master product again after buying this board. The enter key LED wasn't working which wasn't a huge issue, returning the board seemed foolish due to the expenses involved so I contacted CM hoping for a small refund,...

Blue switches, comes with key cap puller, TKL, back feet are fully coated with rubber

Works fine with Linux and Windows, not with OS X ; The customer service is dismal

Can't miss with this...


Don't use supersaver delivery during a snowstorm - lol - my postman reported that it was undeliverable, due to their laziness of not wanting to go up my driveway. Had to order a second one to replace the first, but the first was delivered a day or two...

Ease of use; nice backlighting of keys; totally cool gaming keyboard; bought it as a holiday gift for my 14 yr old tekkie and he loves it so much, I had to order another one for my 13 yr old tekkie
