If you work in a very quiet office and sit out in the open this keyboard might be a distraction for others.  Outside of possibly being distracting this keyboard is FANTASTIC!!!  The keys are very responsive and I'm able to type much faster than on my older keyboard.  I get a great feel and feedback from this keyboard and the price is a steal.  The blue led light is awesome and the build of this keyboard is solid.  If I knew that a keyboard would respond, feel and sound like this one does I would have changed out my old keyboard a long time ago.

Update:  I had bought a different keyboard for the office, $120 with Cherry MX Red switches and it felt mushy so back it went.  I bought another one of these EagleTec's for the office and it feels great.

So it's a keyboard. Yep, you press keys and things appear on the screen, very much like what I'm doing right now with it.

Generally, this is a very good keyboard. I have no huge complaints. However, there are a few niggling issues that should be brought up.

1.) There's no stand on the back of the keyboard, so unless you like very flat keyboards, stay away.

2.) There's that nasty reflective plastic used around the number pad attachment and the arrow keys. It gathers scratches pretty easily, so be careful with it.

3.) The normal small alphabet keys make a satisfying enough sound when you press them, but the larger keys, such as the space bar, enter key, shift keys etc sound VERY clacky and cheap. The space bar in particular is very distracting in sound. Definitely not in the same league as the Logitech DiNovo keyboards.

4.) The macro keys take some getting used to. I question their use only because Microsoft is bound to replace this attempt with something in the near future, and then you'll be bound to learning another new macro configuration if you choose to upgrade. If you buy this keyboard and no others, then ignore this point. :)

But there are things to like!

1.) Very easy to switch the number pad to the left or right of the keyboard, and installing it takes just a second. Snaps right in!

2.) The light-up keyboard is quite fun, and not blue, most importantly. Red is fairly easy on the eyes, and blue is a very harsh color, so be grateful Microsoft were smart about this.

3.) It works with a Mac! No, you can't program the macros since there's no software for the Mac, but you can use pretty much all the other keys, including volume up/down, play/pause/next track/previous track etc in iTunes! I wouldn't go out of my way to use this on a Mac, but if you dual-boot Windows/OS X, go for it!

Overall, a very decent gaming keyboard. I enjoy using it quite a bit. :)

4/5.

I absolutely love this keyboard. As a professional software developer and occasional writer, this keyboard feels amazing to type on and the volume control and magnetic bar make it even more seamless to use. It's definitely loud though so keep that in mind when purchasing it.

Just a note: this review is for the keyboard only, as I'm using a Logitech MX700 for my mouse.
This keyboard is excellent, but just has one or two things I don't like about it.  First of all, I love the natural layout.  The multimedia keys across the top are great, and I'm glad someone finally put a calculator button on, as I use it from time to time and hate going through menus to find it.  Points for the Media key, which brings up your preferred player.  Some people have said they don't like the delete key: I do, I hate having an insert key there.  Having the ctrl shortcuts on the board are very nice too.  Only a few things I wish they'd change: first, as noted by others, they should have F-lock on automatically.  It'd be nice to have the lights for the locks on the keyboard itself.  The keys are a little noisy, but nothing that's too loud.  And finally, having one of the mm keys open your sound card drivers would be a nice addition to the sound keys.  Overall though, it's a great keyboard and I'm glad to have it.

I truly love this keyboard I do!! Here are my honest opinions on this. I'm not giving it a 5-star review...yet. I haven't had it long enough to say that for sure. As for now, I'm loving it! I actually went to big name electronic store and bought the Apple keyboard for my iPad Pro. Spent $150 on it. I hated it from the word go. For one, in order to use the keyboard I had previously purchased, I had to remove my iPad from its Otterbox, and then place the iPad in this case that was held up with a triangle shape in order to connect the iPad with with its three contact points and that drove me bonkers. That right there was the first  moment. I'm a college student who is using the iPad for my notes in classes, and fumbling around getting things set up to take notes with books and iPad and all that in short amounts of time proved to be a hazardous thing when I attempted to use it in class once. I nearly dropped my brand iPad and had I did, the concrete floor beneath the tiles would not have been nice to my iPad. Second major thing...the Apple keyboard in comparison feels like it's going to break. It feel extremely flimsy and fragile for something that cost me $150 and was an Apple product. I love Apple products. My whole family has iPhones because their iOS systems are much safer with the virus, spyware, and "bug" typical androids and even PCs get. I bought this keyboard because I needed something quick and something that was Bluetooth capable. This keyboard being Bluetooth compatible is a HUGE plus. Having the Otterbox for the iPad and it's hard shell casing, the casing actually is a stand. I think the only thing I would like to see as an improvement (so far) is maybe a possible way to have rechargeable batteries or battery pack for it (similar to a cordless home phone thing) in it l, or even a way to recharge it via a port of sorts (longer lasting than basic AAA batteries) to charge it say with a battery back (like cordless phones?)  I enjoy the sleep mode for the most part, except when it's in my bag and I forget to actually turn it off...it runs the battery down quickly.

My biggest happy face in this purchase is the actual "feel" of the keyboard, especially in comparison to the apple one I bought. This keyboard has the feel of a real keyboard like attaches to a computer. I type faster than I write for notes while in class (50-60 wpm on average). This keyboard keeps up well with response to my typing speeds and needs. I'm quite impressed so far, and look forward to continuing to use this at a fraction of what I originally spent.

The first microsoft keyboard I used was white, not sure it was called the "4000" but looks identical, when I wore the first one out there was no doubt what I was going to replace it with. I use this keyboard at work where LOTS of typing is done, at first the keyboard feels odd with it's shape but after a while of usage I cant go back to the plain jane straight keyboards as they hurt my wrists for long typing sessions.  I WISH Microsoft would make this keyboard with BACKLIT keys! I do a lot of surfing in the dark and backlit keys are a must! Im planning on purchasing another one soon as I have worn some of the lettering off the keys, I may even stash a few of these in a closet as I suspect they will either discontinue this model or change it in the future. I cant stress enough how awesome this thing is for WORK, once you overcome the "weirdness" it will rock your world  and your wrists will thank you!

Absolutely love it! The keyboard does not have that silcone cover on top and it has arrow keys and such. However, I thought I had a bad one until I realized that I had to click the button that looks like WiFi in the corner.

...let us ding DAS for sending out keyboards with the notorious "squeaky" backspace key.  What began as a minor nuisance grew to be a "keycap puller and lubricant purchase"-inducing and uncompromisingly irritating annoyance.  Rumor has it that this is a common issue with mechanical keyboards.  Caveat emptor.

From the perspective of a Mac user and a first-time mechanical "keyboardist":
The keyboard itself is phenomenal. The key response is sharp, and I am never switching back to working on a membrane keyboard.  Recommended to the utmost.

My only quibble/suggestion:  go ahead and add a keycap puller and non-corrosive lubricant  (google-search the right type) to your cart along with this fantastic keyboard.

I'm writing this review using that awesome keyboard, and i must say that this product is just amazing. accurate noisy typing keyboard that do just what it is supposed to do.
pros: awesome volume control wheel, fast typing speed, accurate lights for dark times while also clearly visible with the room's light turn on.
i love the sound, the feeling of the keys. the metal frame, the 'turn windows key off' key, and the variety of light options it gives.
cons: no hand rest, but if you have a good computer armrest chair its just fine that way. the enter key is too small in my opinion. id prefer the full sized enter, but that's something to get used to.
except that, 9/10.

I would give this 4.5 stars except for the insane fact that Esc requires the Fn modifier key.  This is due to their decision to default to the specialty keys (i.e. home, cut, copy, paste, back, play, forward, etc) instead of the F1-12 keys, and including Esc in this arrangement.  Del(ete) mercifully does not require the Fn key.

Everything else about this keyboard I love!  The battery life may be a bit short, but it hasn't really bothered me over about a month of use.  It does take ~5 seconds to wake up after the first keypress, but this is true with most wireless keyboards, including the apple bluetooth keyboards I've used.

The variable color backlight is unnecessary but fun - I wanted backlighting but did not need different colors.

The typing/key action feels great actually, and that is the main reason I got a keyboard after all.  If that hadn't been so excellent, it wouldn't have mattered how nice everything else is.

I am a fan despite the Esc key nonsense, and I use Esc a *lot*.

The keyboard is great..... However you need to train yourself to not touch it accidently!

I bought this for my wife and she loves it! I, personally, have never cared which keyboard I'm using. They were all the same to me. Until I tried this one! I am not sure I can describe it but, the keys move smoothly. You know when you have hit a key because they push back against your fingers with just the right amount of pressure. In fact, I told my wife I would like one for my birthday.

Great looking / performing keyboard would rate 5 stars if it wasn't for the spacebar problem that allot of peoplE are having seems like it really interferes with typing every time i have to press it.. as long as I press it directly in the center it fuctions amazing l like the other keys but if you don't or youR typing fast it.doesnt seem to want to function correctly I still love thos product hopefully the spacebar well get better with time

It's really nice. I may seem weird but I find the loud clicking sound of the keyboard satisfying(Its really loud).Nothing seemed broken or out of place,other than a few smudges that I could just clean up.
One thing I found to have a chance of being out of place is the LED for the logo at the bottom. It seemed to shine from the top snake rather than straight in the middle and bothers me sometimes.
Other than that,a keyboard is a keyboard,and this one is cool!

I was on the fence due to some reviews, but I am almost 100% happy. My one downside to this keyboard and case is that  the tablet can slide backwards when propped up to use the keyboard. I love the touch and feel of the case and real sensation of the keyboard. Keys are very reactive and keep up with my typing. So worth the $30 price tag!

I bought this a day after I bought my Surface 2 Pro, not because the touch keyboard was bad but because I missed having a keyboard, not to mention without a keyboard it's pretty hard to game, although until now I had just been using xpadder + x360 controller.

I went from having around 4-6 hour battery life to a 16-24 (if everything is being utilized 100% then I usually get below 10 hours) hour one (at one point I got it to last up to 48 hours but that was an extreme attempt, I had disabled as much as possible, put brightness down to the absolute minimum, everything economy mode/power saving option was active and on. (Still though! 48 hours!)

The keyboard took me two days to get used to completely (back to not having to look down at the keys, missing keys or losing my orientation around the keyboard.) the *ONLY* issue I have is with the trackpad, I have no idea who's idea it was to make the trackpad the same material as the rest of the keyboard (excluding the actual keys, the entire keyboard is in this suede material and--although the trackpad is outlined with a slightly shiny material--you are rarely able to see the trackpad ever, in a well lit room it will be slightly visible, and in a dim room you will likely not see it at all, from any normal typing position. The fact that the left and right mouse "buttons" are just areas on the trackpad with outlines around them to make them look like buttons but are in fact just part of the trackpad surface (a section) which if you tap on it--will perform the function of the left or right mouse click. So again, if you close your eyes and try to use your finger (relying on only one sense (touch/feel)) you will not be able to orient yourself. Everytime I'm going to use the trackpad I actually have to look at it, and where my finger is, to orient myself and be able to use it with precision. (so I basically use the touchscreen even when my hand is mere centimeters from the keyboard's trackpad.)

The trackpad removed one star by itself, the battery life added one by itself, and even though I would have loved a backlit variant (of this keyboard) the battery life is just too good to allow me to take away another star from this product. Seriously, even though it isn't backlit, and the trackpad is bad. Buy it. The keyboard is pleasant to type on (just slightly compact so you'll need to adjust to it--at least I had to, it took roughly 2 days, not a *conscious* effort though.) and the battery life will open up so many possibilities in the real world. Like being able to program while I'm out and about with my girlfriend and her family, we go across the country to meet my mom's side of the family and her parents family. Driving across country being far from an outlet and with the car's charger port being used for other things, it means I'm relying on hotel rooms and restaurants/stores/etc with outlets. Now however, I can sit on construct 2 while listening to jazz, writing down ideas on Onenote while syncing old notes from Evernote--and tweeting mindless statuses in 140 characters or less--all while knowing my battery life can last me until the next, next hotel room! I haven't been this relaxed on a trip for a long time.

This is a seriously awesome keyboard!  I have smaller hands than most people, and couldn't get into piano because my fingers were too short, but this keyboard is AMAZING.  The left arrow sometimes gets pressed by mistake, which leads to some fun autocorrect issues, but apart from that I am constantly amazed by the feel and functionality of this keyboard.  It's BEAUTIFUL, and it fits on my desk so well.  Great work, Logitech, everyone else just GET THIS KEYBOARD!  You will not be disappointed ;-)
