What customers say about "Size & Weight"
Corsair K63
  • The small form factor of this keyboard was what attracted me to it in the first place.
  • I was able to easily find a case for the keyboard and I am happy with the size.
  • Nice overall and hardy plastic with the typical Corsair branding. The K63 has a tight butt fit into the enclosure. The mouse pad is nicely sized and functional.
  • I'd rather this thing was either smaller or had a full size keyboard.
  • Mouse pad is good size so you can actually play FPS games well without feeling confined with your mouse movements.
Corsair K70 Rapidfire RGB Backlit Mechanical Keyboard
  • The K70 is a full 104-key keyboard and it has the size and weight to show for it.
  • Also it’s full size with a number pad which is also a big plus.
  • It has a very premium feel as it's aluminum and has some weight to it.
  • Plenty of weight makes it feel secure. Rubber feet keep it in place well.
  • Because of its weight the keyboard doesn't slide around on my desk, there is no feeling of "cheapness" or of being flimsy.

What customers say about "Keys"
Corsair K63
  • Having a mechanical keyboard has been a dream for me for quite some time and this keyboard did not disappoint.
  • I love the way the keys feel. I've only owned one other mechanical keyboard (razer blackwidow) but i prefer these.
  • The lack of the 10 key number pad has been a great improvement for me, I don't know why I didn't make the switch earlier.
  • The key press feel is nice and dependable. A bit louder than I would have liked, but not a dealbreaker. Key caps pop off easily without the need for a key puller (one is not included).
  • The Windows lock key failed within weeks.
Corsair K70 Rapidfire RGB Backlit Mechanical Keyboard
  • Enlarged letter sizes to enhance lighting effects.
  • Since I do a lot of typing at night. It's nice to have backlighting. The lighting has 3 brightness levels.
  • I used to think backlighting on keyboards was pointless until I discovered this one. I just use the red one which is the cheapest because red lighting is the most gentle on the eyes, especially at night when you are most likely to actually need the backlighting.
  • The multimedia keys and pass-through USB are a big plus. The keys easily work with my iTunes and I have not had any problem using them.
  • The multimedia keys and volume scroll wheel are just the icing on the cake.
  • The keys stick out really far since there's no bezel around the edges of the keyboard or around the outside of the keys even. You can't pick the keyboard up to reposition it without pressing keys. The keys around the edges seem very susceptible to damage with no protective bezel.

What customers say about "Features"
Corsair K63
  • Having a mechanical keyboard has been a dream for me for quite some time and this keyboard did not disappoint.
  • A comprehensive array of macros can be set using the software, making the keyboard very flexible.
  • Average battery life with LEDs on is around 24 hours and with LEDs off is around 72 hours.
  • The memory foam bottom makes it feel like you have a simple pillow on your lap
  • The wrist rest on the lapboard and the one that comes to use if you want a normal keyboard do a good job to minimize wrist strain
  • I was a little disappointed that you could not set specific keys to be illuminated, but this was a small niggle.
Corsair K70 Rapidfire RGB Backlit Mechanical Keyboard
  • Comes with a removable wrist rest that tilts depending on the incline of the keyboard. It's very easy to snap on and off.
  • The keyboard has little pop-out tabs for supporting the keyboard to tilt it away from you if you're using the wrist rest, and towards you if you're not (though I highly recommend you do use it). They're strong, and they won't break off.
  • Software is available for Windows which allows you to animate they keyboard but on Linux you'll have to settle for the default red.
  • The palm rest was a must for me personnaly and it is very comfortable.
  • It also has a strong tilt forward that I do not like. setting the front feet up levels the keyboard, but makes it feel even taller.
  • The biggest issue is all the big keys such as space enter and shift are not balanced properly. Meaning if you press on one side of the key cap instead of on the center, the key tilt by a lot.
  • The only problem I got is when I used the software on windows 7, it became unusable, and since I got no free usb 3 on the PC in that moment, it was very horrible to use with compatibility for BIOS, it somewhat hanged (Well, also my PC was very old.).
