Best keyboard i know of

Well i was searching for a keyboard online for a [less expensive] used price. And i found one. I was not specifically looking for a microsoft one, but i was hoping on getting it, and well i got it. When i was looking for more info on the keyboard i noticed that i couldn't get much info, especially what are the buttons functions, so I am going to tell you it. There are 19 buttons which do activity's. The activity's are or as microsoft calls it the Hot Keys are Back, Forward, Stop, Refresh, Search, Favorites, Web/Home, Mail, Mute, Decrease Volume, Increase Volume, Play/Pause, Stop, Prev Track, Next Track, and Media(lists all entertainment type programs such as real player, winamp, cd player etc.), My computer, Calculator, and Sleep. I found that the only buttons you can change the activity with is the mail button, calculator button, my computer button, and search so far. The detachable palm rest is not comfortable as my other palm rest so i don't use it. The keyboard lists keyboard shortcuts on the side of the corresponding keys such as if you were trying to copy a word you would press cntrl+ c, and on the side view of c you could see it says copy. The keyboard comes with PS/2 and USB cable joint together. The keyboard has a built in 2 usb ports. The keyboard allows you to disable some keys, if you wish to. Well I liked the keyboard, and i bought a used one, and found a great price for it too...

Okay going to make this simple.  I do IT work and have been through a million keyboards.  Do yourself a favor and buy this keyboard it's the last one you will ever need!

I've loved this keyboard so far. The clicky feel makes it better, I love typing with this keyboard. It feels so accurate than any keyboard I've tried.

I've been using these for years, and I honestly can't imagine buying any other kind of keyboard. I love this so much because of all the function buttons as well as the keys being fairly quiet when compared to the competition. When you work all day on the computer, a quiet keyboard is a MUST!

This is the best keyboard ever in my opinion.  The separation in the keys allow me to not make less mistakes.  I had no idea how much I would need the backlight.  Plus, it's nice being able to charge it rather than getting batteries for my Apple Bluetooth Keyboard.  Plus, the three different bluetooth buttons are great.  F1 in my computer, F2 is my iPad, and F3 is my iPhone, and IT'S INSTANT!  One problem is I connect figure out how to skip songs on iTunes, but I keep forgetting to figure it out.  Even if I cannot, it's definitely 5 stars, especially at $79.  FYI - I would just get a new bluetooth keyboard instead of trying to save $20.  I bought an used Apple Bluetooth keyboard and a new one really made a difference.  I feel it would be the same with the Logitech, and think about how much you use it also.

amazing keyboard. I'm currently using it as I type this. so many light settings and the keys feel amazing. I have no complaints, and I suggest it to anyone who want's something of quality and not paying over $100 on a keyboard. It's just as good.

This keyboard is hands down the best keyboard I've ever had. It's VERY loud and the mechanical nature of the keys are very pleasing to the touch. It's perfect for general use and/or gaming (which is what I use it for). It's been amazing with no problems whatsoever. (I've had it for around 6 months so far).

BUY IT!

Best typing keyboard I ever have. Personally I like Matias' switch better than any one from Cherry MX. Alps rocks.

It's not my first one. But I would say MsNEK 4000 is the best keyboard ever.

Just got my new keyboard yesterday and I love it soooooo much. I love the blue LED back-lit keys. The fact that they give you clear keys and a key remover to change them, is amazing. The style is very similar to my old keyboard, which is by far my favorite keyboard ever, next to this one of course. The keys are easy to press and have very little resistance. I am very happy with my product and will buy another if this one goes bad after a year or two. I may even buy another for my other computer.

Best Keyboard I have ever laid my finges on. The keys are quiet, easy to push and the layout of the keyboard is one of a kind. I highly reccomend this keyboard, heck its only a few bucks and deffintely worth it.

One of my favorite keyboards, even over my corsair, logitechs, and razers. Prefer the redragon switches over the standard blues.

Have been using this for a while now, and I absolutely love it. Got it with the brown switches, and it's the best move I ever made, perfect balance for the not pro gamer. Reds were just too sensitive for me, and the blues too clicky/noisy. Browns are a perfect sweet spot. The software to program the RGB keys is phenomenal, super easy to use and responds well, comes with great presets and profiles are easy to switch. Keyboard itself is extremely solid and all the keys light up well. The keycaps they give you for swapping out are very nice, the extra grip/feel is awesome, I only wish there was some MMO keys included to swap my 1-5 keys at least, they only give MOBA and FPS. The USB passthrough has it's own cable, well labeled, so if you don't want to use it, it's easy to leave out. Best keyboard I've ever owned.

I've had a few - this one is the best.  With Cherry MX key switches its a really solid device.  Razer's software works well too (I know it had problems in the the past - but for me it has worked flawlessly).

coming from cherry switches (MX browns/Blues) this is a lovely to type on but for games like sc2 where I need to be fast the initial (push) on the keys makes me feel sluggish sometimes but for typing and other games such as FPS this is a very nice keyboard and would recommend topre switches to others.

UPDATE

It's been over a year and a half and I can say that after getting used to the switches I don't think I could use anything else. This keyboard is great for everything. Typing. Coding. Gaming. You name it, I would easily buy this again if this one broke for what ever reason but I doubt it will anytime soon considering it's still rather new.
My only gripe is SOMETIMES and this is rare like once every few months. My computer won't realize that it's connected. but unplugging it and plugging it back in fixes it. (Might just be windows...I don't know) And I have never had it disconnect on me, Or anything. damn near 100% reliable.

It's a rather expensive but for how long I intend on having it. It's worth it.

I have tried other keyboards and by far this is the best.  For the money you can't beat it!  Only drawback is I do wish it had a clasp to keep it closed.

I love this keyboard. One feature that really surprised me was the NKRO over usb. I can press as many keys on this keyboard at one time and they will all register (which is something I had thought to believe was impossible over usb, this is the only keyboard I've seen do this). I was a little disappointed that I could not use my PS/2 adapter but oh well. It cool that it only occupies one usb port on your computer and has two usb hubs. The lights are great and I love the color. I had to send this keyboard the first time I got it back to the manufacturer because it died on me but after a few weeks they sent me a new one and I haven't had any problems since. I'm staying away from the macro software though cause I think that's how my first keyboard died . I would have liked to see the option to have more then 5 macro keys. I also think that the function keys like volume up/down should be on the right of the keyboard rather than on the left. The cherry MX red keys take some time to get used to. I love how they keys are't clicky so they don't make too much noise. I made and still make accidental button presses with this keyboard because the keys are very sensitive, you don't even need to push the key all the way down before it registers. I think I would like to see this keyboard with cherry MX black keys because sometimes I think the cherry MX red keys are too sensitive. The keyboard also comes with headphone and microphone ports but I don't use it because you can hear interference when you dim the lights on the keyboard through the speakers that are connected to it or headphones. I think maybe in the future they can shield the wiring so that does not happen.
