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...

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

Great Keybaord


Love this keyboard

Looks nice ; Nice feel to keys ; Very responsive ; Sturdy does not flex easily

Easy to make typos ( but not really a con)

Consumer review by:



Love this keyboard. Got it when it was on sale for $70. WORTH ; Back lighting is very vibrant. Extremely durable feel

The number pad/ arrow keys take a while to get used to. Only thing I wish was different is the enter key on the numpad only works if numlock is on rather than all the time

Pretty good


Nice, clicky, responsive, tactile, and small but not too small

A single key (the I key) doesn't click exactly right. I'm able to fix this temporarily by putting a small drop of water under the switch (don't do that. Seriously.) ; This issue isn't really worth knocking off an egg or replacing the product. It works...

Not worth the money.


Won't be buying a cooler master input device ever again.

Cool design ; Compact board ; Nice LED settings ; Not that loud for a Mechanical board

Only worked two times ; Not worth the money, can go for a more affordable board and get more reliability from a cheaper board

Overall great board


I can repeat what everyone else has said: Solid backplate construction, quality key material, and great compact ; fully mechanical keyboard for a good price. I tested every key and led out of the box with no hiccups ; Now that that's out of the way, we...

None of these are real cons I can take an egg off for. These quirks are more slightly annoying details you ; won't notice unless you are easily irritated ; FN Lock ; This also could be considered a con, in that it only takes three seconds to lock the...

Perfect for small hands


I have been looking for a mechanical keyboard that will fit my small hands for quite a while now. The Quickfire TK Mech is perfect for me ; My palm is only 4" to the base of my middle finger and my middle finger is almost exactly 3" inches long, which...

I got this on sale for $69.99. I would not pay full price for it because it seems to require a USB 2.0 plug, which motherboards may not support for the entire life of the keyboard. Additionally, it comes with no software or other hardware features that...
