Reason 1: Firmware update bricked the darn thing. I have no way of resetting it.
a) It is ridiculous to have to download 120 MB setup file just to assign colors to keys.
b) Key colors are not permanent (you cannot save them to the keyboard). It means you cannot use the keyboard with less popular OSes --such as BSDs and others.
c) In order to use custom colors, a Das Keyboard Windows Service has to run in the background and it has to be able to connect to the cloud/Internet.
This is an incredible security issue. I have no idea what that Windows Service is doing. It might as well be a key logger.
Who knows; it probably is. After all, who would go to all the trouble of writing a cloud-connected configuration utility just to assign colors to keys.
In short: This is supposed to be a keyboard. I should be able to save custom colors to it --not somewhere in the cloud. All the rest are frills.
If it cannot do that basic thing, it is a useless piece of crap.
Waste of money --unless you want a potential spy in your computer.
I don't understand why everyone is raving on about the "quality" of thing thing. This really doesn't feel all that different from a $50-60 Logitech you could pick up at your local electronics store.
Also, because the keyboard is so wide and much bigger compared to the "Magic" keyboard, I feel like I am putting much more effort in to reach for the mouse after I am done typing.
I'm going to use the keyboard for the week and hope I get used to it, I'll update my review then.
EDIT: Nevermind, I tried going back to my old keyboard and it felt like mushy garbage. Two days in and I'm actually loving this thing now. Haha, who knew???
First, let me say the keyboard is sweet. Build quality is top notch. My only complaint with the design is that the I would like a bit more of an angle than the ruler provides. But that may just be a personal preference.
I had a switch go bad after about 5 months. I reached out to support and they did offer to repair it, but their terms were unacceptable to me. They wanted me to send them the keyboard at my cost for 10-15 days, then they would return it at their cost. Maybe I am being out of line, but I can not go 15 days without a keyboard, and I don't think I should need to pay anything to get a $160 keyboard fixed that is still under warranty... I would much rather them ship me a replacement and a prepaid label for my old one to return.
Mid-range keyboards from reputable manufacturers still build upon the rubber dome actions, so even upgrading from OEM or $12 keyboards to the $40 - $50 range significant improvements in the action are not found. So again, we are duped into settling with mediocrity.
There is hope out there. Cherry MX switches, Topre switches, and other mechanical style switches are being manufactured for keyboard actions. They're expensive compared to rubber dome keyboards. Each key has a mechanical switch of some sort beneath it, rather than a sheet of heat-molded rubber domes. And the mechanical switches are made with precise characteristics -- softer, firmer, clicky and tactile, non-clicky and tactile, and smooth linear. Each style is designed with a different market segment in mind; linear being the preference of gamers, tactile (clicky or quiet) being the preference for those who's keystrokes produce text, softer for light-press typists, and firmer for mashers.
The Cherry MX Brown is a soft, tactile, quiet key, with a subtle bump at the actuation point. With practice muscle-memory is able to get accustomed to that bump, and users become able to type without bottoming out the keys. Typing speed and accuracy often improve, and finger fatigue is reduced compared to typing on keyboards where you have to bottom out each stroke (rubber domes, for example).
I debated back and forth between this keyboard and one from WASD, and ultimately went for the Das-4 because of the sturdy aluminum face and USB3 hub. It arrived today and I've had a chance to put it through its paces. While it may take a day or two to get used to the feel, it's going to be a pleasure getting there. Lifting it, the keyboard feels like a tank. Typing on it, the keyboard feels absolutely fantastic. However, I may still add 2mm O-rings to reduce clatter, though I'll wait until I've gotten more accustomed to the tactile feel of Cherry MX Browns. It's possible I'll develop more of a habit of not bottoming out my keystrokes.
This sounds too predictable, but when I first plugged it in and began typing on it my first notion was "Wow!"
Pros: Heavy and sturdy like you might imagine a keyboard in a 1960's NASA mission control center. A light, tactile, pleasing touch with ample stroke and precise response. The tactile bump of Cherry MX Browns allows me to type without bottoming out the strokes. Already with a little practice my typing is feeling more effortless. USB 3 hub. Nice, sturdy media controls with a well-engineered volume knob. Beautiful design. If there is a better feeling and better engineered keyboard on the market, I sure can't find it. The keycaps are crisply engineered, flawless, and elegant.
Cons: Because it is built to last, and made of metal, bottoming out keystrokes makes a bit of clattering that you wouldn't be accustomed to if you have spent years obliviously enduring the misery of rubber-dome keyboards. A set of 2mm O-rings would alleviate that issue, and they are easy enough to order. It's too bad the keyboard manufacturer doesn't make O-rings a special-order option as WASD does. Another con is that the keyboard's elevated support is a little on the low side -- the keyboard sits slightly flatter than I would prefer. But after a few hours I'm already getting used to it. Nearly every mechanical keyboard has a spacebar that seems to stick up a little higher in the air than space bars for dome keyboards. That takes a little time to get used to as well, but after awhile will begin to feel normal.
Conclusion: If quality and feel are more important to you than price or RGB lights, this keyboard must be on your short list. The keyboard seems to strive for elegance, feel, and function while eschewing trendy light shows and annoying color schemes.
Updated 2/4/17: I've been using the DAS Keyboard 4 Professional with Cherry MX Brown key switches for a few months now. And I even installed first WASD red, and later WASD blue O-rings to further customize the feel. The keyboard feels so nice to use I barely notice it's there. It's a pleasure to type on. ...and then I go home from my office, and when I sit down at the home computer I place my hands over the mid-range "rubber dome" style keyboard, and loathe every moment. The solution? I ordered a second DAS Keyboard 4 Professional and a set of WASD blue o-rings. One at work, one at home. Great keyboards!
Updated 9/30/2017: I've been using one of these at my office, and one at home. The one that has had the most use is in my office. I'm a software engineer, and type all day long. The key caps have become a little polished, but the symbols have not faded at all. The key strokes feel as good as the day I got the keyboard. ...maybe even a little better with age. It's my "daily driver". Recently my company provided a second office for me a little closer to home, with the understanding that I would split my time between the offices. For my third mechanical keyboard I ended up going with a Logitch Professional (tenkey-less, with Roamer-G switches). The Roamer-G switches have a slightly shorter keystroke, and the overall feel of that keyboard is more plastic. The Roamer-G switches don't allow for o-ring installation, so it clatters a little more too. But I had to try something new. One thing I can say for the Roamer-G switches is that they feel smoother right out of the box than Cherry-MX Browns. But with age the MX Browns acquire that smooth feeling too. Overall I'm convinced that I like the Das Keyboard better. (A few weeks of use and I have to conclude the MX browns are smoother, and feel more high-end. Sticking with browns in the future.)
Update 12/2018: I now have the same keyboard with Cherry MX Blue switches. I put blue O-rings under its key caps to reduce bottoming-out clatter. It took longer to get used to the click blues than the subtle browns, but I also like them very much. If it weren't for the fact that the noise level using blues is higher than when using browns (disturbing to others but gratifying to the typist) I would have to say for typing I prefer the nuanced qualities of both. The blues feel a little more crisp, slightly firmer. Browns a little less tactile, and a little softer touch. Both are excellent. If you don't care about making some noise typing, and want additional crispness, get the blues.
If you are a gamer do not get the blues, as their reset point is higher in the stroke than the contact point, making them slower switches for rapid bouncing on a single key. Totally irrelevant for typists.
Browns: softer touch, more subtle tactile bump, quieter. Blues: clicker, more crisp feel, slughtly firmer spring. Both, excellent.
Update 6/30/2020: I have three of these, now. One at each if my two offices, and one at home. Two of them are MX Brown switches (soft tactile) and one is MX Blue (soft tactile&clicky). I got the blue on accident (thought I was ordering a brown), but kept it and love it too. I've now been typing on these since 2016, and they're still as good as new. The key caps are easy enough to remove for the occasional deep cleaning, but if you avoid spilling drinks on them these keyboards are built to last. They get plenty of use, but aside from the key caps having a more polished look to them you would barely know they're several years old. And the laser etching is still intact. The switches still feel great too.
But there's one seriously idiotic flaw. The feet.
Somebody had this inane idea to make the feet a magnetic ruler that sticks on the bottom. Except that it doesn't stick. Pull the keyboard towards you? Falls off. Push it back? Falls off. The tiny rubber constraints do nothing to keep it in place.
It just baffles me that an otherwise perfect keyboard could have made it through testing without somebody saying "a magnetic ruler as feet for a keyboard? what the heck?"
Just give me the normal feet back please...
2019 update: after supergluing the feet to the keyboard, no other complaints. I have the blue at home and the brown at work, and they've both been working flawlessly every day for years now.
Top reviews from other countries
Build-quality wise, this keyboard screams premium from a thousand miles away. The top panel is made out of aluminum and looks very pretty. The entire keyboard is very solid ( and heavy). I love the volume knob on the top right, it is sitting at the best position possible. The footprint of the keyboard is rather small for a full sized one. Keep in mind this is more oriented towards professionals, rather than gamers, so there are no macro keys and no RGB fluff.
The cherry MX brown switches are exactly as I expected them, they give the same feeling as the blues that I have tried before but without that much noise. It's still more loud than a traditional membrane keyboard, but not by a big margin.
I like every little detail on it, from the very professional letter font, to the LEDs that are dim enough to not attract your eyes every time you look at your keyboard.
Pros of this keyboard :
1) It sports a very minimalistic design with no fluff.
2) Media keys on the correct spot.
3) Cherry MX browns are awesome.
4) Long cable which can be useful depending on the situation.
5) USB hub( haven't needed it yet).
6) full NKRO
7) No drivers or any kind of extra software needed, something which has been crucial for me.
1) No backlight ( I personally don't care about it).
2) The ruler that acts as a stand is a funny novelty that doesn't do the trick as well as I would like it to do since it doesn't elevate the keyboard enough.
3) The cable to connect the keyboard to the computer goes off right on the middle of the keyboard with no way to redirect it, which is something that might bother you depending on your setup.
4) The cable is not braided. It doesn't really matter in terms of durability since it's thick enough already, but given the price it would certainly feel more premium if it actually was.
5) If you plan to replace your keycaps for fun and aesthetic reasons, keep in mind that the company's logo and the volume knob both have red accents, which might limit you in terms of colour choices for your keycaps.
6) Lastly, and this is kind of important, the cable is not detachable, and this might be the only weak point of the keyboard in terms of longevity. The point that connects to the keyboard seems sturdy enough, but these have failed me many times before in various products, so I can't be sure right now.
Would I recommend this product ? Yes 10/10 I would recommend this to the professional buyer.
Also, PLUS points because this came with a bag of Haribos inside. ( Yeah, no kidding).
SOLID. The quality is excellent.
I love laptop keyboards with a short travel distance and it toom me some time to get used to it - not a deal-breaker.
The things a love ❤ about it:
1. Heavy. It sits tight on you desk.
2. Super-premium look 😎 and feel
3. Build-in USB 3.0 ports
4. Mute button is super-handy when it comes to listen to some one. Easy to reach - one light click and you are listening to a person who is talking to you.
5. Toggle when - extremely pleasant to use. It have a nice feedback when you scroll it. Excellent location. Easy to reach whatever your hand is on mouse or a keyboard.
6. Ruler - there is red magnetic ruler on the back or the keyboard which is used as a stend. Nice little feature. It's plastic but feels as a solid piece.
7. Anti-ghost. No interference with any keys.
Things I don't really like 😤:
1. After a couple of years surface of the most used keys weared our and become smooth instead of having the same "gripping" texture.
2. Ruler don't have slipping pad and keyboard moves some times (not a deal-breaker).
3. I had to buy wrist pad to make my wrist comfortable and level it up with they keyboard.
4. No O-rings in complect. Without it keyboard sounds to me too plasticky. With O-ring the sound is deeper, more quiet and more suitable for the office. No complains sound level is ok.
5. No RGB or any other backlight.
Overall it's a great keyboard which is a bit overpriced. However this is a solid piece of professional equipment suitable for day-to-day work and decent gaming.
Worth its money.
As for the downsides, after 2 years of use;
* Some keys, notably the left shift key, have lost a lot of their satisfying clickyness.
* I was hoping the key caps themselves might be made of metal too, but alas they are made of plastic.
* The writing on the most commonly used keys (A, S, W, D :D) has slightly faded already.
- No drivers or firmware to worry about. Fully compatible on GNU/Linux.
- Very sleek minimalistic design. Blank key caps look cool. No glossy surfaces to attract fingerprints.
- Keyboard feels very solid with top metal plate. The magnetic ruler is unlikely to ever break unlike keyboards with leg stands. Volume knob feels very nice witch notches for each adjustment.
- Cherry MX Blues are very satisfying to type on.
- Blank key caps will force you to learn touch typing and will make you a better typist. But they are sometimes challenging when looking for that symbol you rarely use.
- Quality Control is not great. Some of my keys feel different, 1 key is mushy and doesn't even feel like a mechanical key.
