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...

Bad support - Worse product.


I purchased this product on 9/12/2014. At first I loved this product, my first mechanical keyboard with the famous cherry reds. I purchased an Razer OrbWeaver and needed a compact keyboard to fit on my smaller desk. Anyways on 10/14/2014 the product...

Cherry Reds, nice backlight, compact

Terrible customer service, braided cord tightly wrapped

now blacklisted


cherry mx blue switches, smaller form factor

let's start with no matter what I do I can not get this keyboard to connect with a computer(1150 maximus impact vi, am3+ MAX PRO R2.0) without 15 minutes of fiddling after it has been shut down. I have tried everything with a ton of advice. another...

Really Amazing Keyboard


This keyboard has amazing Cherry MX Blue Switches and it feels amazing to type with it ; If you type or game at night, the backlighting on this keyboard is amazing ; This keyboard is very compact and I can take it with me anywhere I want to, while...

The arrow keys are actually part of the numpad, which requires me to switch from num lock and no num lock, but I can understand that this was so that the keyboard was compact and could be taken anywhere

Almost Perfect


Overall a very nice keyboard. The downsides I have put down aren't too bad and are more so nitpicks. I think it's a great deal for the price for those looking for a cherry blue compact keyboard.

1; feels amazing, both in typing and the build quality itself ; 2; improved my typing. I went from an average of 85 words per minute on a laptop to 100 words per minute ; 3; compact size works well for me. I wanted a number pad but I didn't want a huge...

1; It's very loud. While I like the sound, I know that many people will be turned off by it. In that case, I'd recommend getting the browns but I really like the tactile sound myself ; 2; The compromise of integrating the arrow keys into the number pad...

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

Consumer review by:



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

Consumer review by:

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...
