The main question about the Das Keyboard Professional Model “S” is not whether it’s a very nice keyboard: let me get that out of the way by saying it is. The keys are precise and smooth, and the amount of force necessary to generate a letter is far more appropriate than the standard keyboards shipped with most computers.
Instead, the main question is whether the Das Keyboard is substantively better than the Unicomp Customizer and Space Saver, both of which use the time-tested IBM Model M design and manufacturing equipment. The answer is probably “no,” especially when one considers their relative cost: as of this writing, the Unicomp keyboards are $69 and made in the United States, while Das Keyboards are $129 and made in Taiwan.*
The slim keyboard and its housing:
As shown, the Das Keyboard is black and unadorned by anything save a “daskeyboard” logo in the upper right. The keys are matte black with white letters etched in by laser—a nice touch—while the borders are glossy and probably prone to fingerprints and smudging over time. The attractive minimalist design makes the keyboard look like part of a set when placed next an iMac and Aeron, as though it were designed to complement them.
The chief drawback aesthetically and practically is the split USB cord:
Not surprisingly, a picture like this one doesn’t appear on the Das Keyboard website. It’s reminiscent of the Matias Tactile Pro 2, and not in a positive way.
But the Das Keyboard does have two USB ports on the side, which is a useful feature the Customizer lacks. To me extra USB ports don’t make much difference: I taped a four-port, powered USB hub to the bottom of my desk, and that’s where I plug in peripherals, my printer, and an iPhone cord. The hub cost $10.
Each stroke brings a satisfying but muted clack. I like typing on the Das Keyboard. Its keys don’t travel quite as far as the Customizer or Space Saver’s, and it’s also easier to bottom out because one doesn’t have the curious resistance that a buckling spring provides, as described here:
The most widely produced buckling-spring keyswitch keyboard is the IBM model M keyboard. When pressing an individual key, the operator is physically applying increasing force (approximately 60-70 grams of force) against a coiled spring. The spring provides slight resistance, so that you can rest your fingers on the keyboard and not cause an accidental or inadvertent key press. Once the key travels a particular distance (approx. 2.5 – 3.5mm), the spring reaches the “catastrophic buckling” point and produces an audible click at the same exact instance that the computer records the keystroke.
With the Das Keyboard, you can still rest your fingers on the keys, but when typing you won’t have the catastrophic buckling that prevents bottoming out. Consequently, the Das Keyboard has a slightly harsher feel than the Customizer or Space Saver. It seems to take approximately the same amount of force to generate a keystroke, but that’s based solely on feel rather than on testing. There might be an objective difference between the two, but if so, it’s not great.
The key switches themselves appear to Cherry MX Blues, which are explained in greater detail at the link and in this Hot Hardware essay.
These switches are louder, though not enormously so, than the Cherry MX “Brown” switches in the Kinesis Advantage Ergonomic Keyboard or the Majestouch Tenkeyless Keyboard. You could use the Kinesis Advantage or Majestouch Tenkeyless keyboard in a dorm or office without offending those in the same room, but the Das Keyboard is probably too loud for those environments. I assume the “silent” version uses Cherry MX “Brown” switches that are quieter and also appropriate for group settings. To get a sense of how loud each keyboard is, check out this video, which compares the Advantage, Customizer, and Das Keyboard:
What do all these models mean?
If you’ve visited the Das Keyboard website, you’re probably aware that you can buy four models: the “Original Das Keyboard Professional, “Das Keyboard Model “S” Professional,” which I am reviewing, the “Das Keyboard Model “S” Professional Silent,” and the “Das Keyboard Model “S” Ultimate.”
Here’s how the somewhat confusing nomenclature and model numbers work: A Das Keyboard “Professional” means there are letters on the keyboard, like mine; not having any letters doesn’t seem to confer any benefit aside from sheer geek street cred, about which I care less than practicality. A Das Keyboard “Ultimate” is identical to the “Professional” except that it’s blank. The Das Keyboard “Silent” is quieter, presumably due to using Cherry MX “Brown” switches like those mentioned above.
The Original Das Keyboard Professional lacks media function keys, has only a single USB connector, isn’t compatible with KVM switches, and doesn’t have “Full n-key rollover,” which means that if you mash, say, six keys at once, the keyboard might not register all of them. The last feature is apparently useful for gaming.
The differences between the “Original” and “Model S” are marginal and not very important. I’d probably take the original.
The Das Keyboard supports OS X and Linux as well as Windows. A set of Mac- and Linux-friendly keycaps goes for $14.95, which is comparable to Unicomp’s cost for OS-specific keys. You’ll have to swap the Option and Command key in OS X’s system preferences, as described here.
A strange problem
Edit Nov. 12 2009: Thomas Aitchison of Das Keyboard sent me an e-mail saying that the problem I described below is a known bug and that the company is recalling the keyboards in the affected serial number range, so this probably no longer applies.
Every couple hours, a key would stop working. The first time it was the “e:” I typed “swt” instead of “sweet” in TextMate. The same thing happened in Word and Mellel. But when I plugged the keyboard into my MacBook, the “e” was back, and switching back to my iMac also solved the problem. The same thing happened a few hours later with the “control” key. Unplugging the keyboard and plugging it back in did the trick. It happened again with the “p” key.
In addition, the remapped “option” key doesn’t function properly. In OS X, option-shift-hyphen generates an em dash, like this: —. But I had to remap the caps lock key to option to generate that dash. I have no idea why. This hasn’t happened with any of the other keyboards I’ve used with this computer: the Matias Tactile Pro, the Customizer, the Advantage, or the Apple Aluminum Keyboards. I assume this is a problem unique to this particular Das Keyboard or to this Das Keyboard with my iMac. Fortunately, the company promises: “For repair and exchange: no waiting, no hassle. We will ship you a replacement as soon as we receive your shipment.”
A second opinion
My girlfriend used the Das Keyboard for a day and didn’t like it as much as I did: she said she heard a high-pitched squeak. Of the keyboards I’ve tried recently, she likes the Kinesis Advantage best. In comparison to the Unicomp Customizer, she wrote, “WAY better than the daskeyboard. […] It takes a little more effort, and maybe I’ll find at the end of the day my muscles aren’t a fan of it, but for now, it’s definitely better. Feels more solid.”
Even Das Keyboard’s website says that “Das Keyboard compares to the legendary IBM model M. Its best-in-class mechanical gold-plated key switches provide a tactile and audio click that makes typing a pure joy.” They’re right: it does compare to the Model M. Either keyboard is an good choice.
But I’d take the Model M. Its durability is proven, the key travel is slightly better, and it sounds more like a typewriter and slightly less “plasticky” to my ears. It’s about $50 cheaper after shipping. The only drawback is the lack of USB ports, which is minor.
EDIT: I wrote a long post on what I think of the the Kinesis Advantage, Unicomp Space Saver, and Das Keyboard two years later.
* I don’t highlight where the keyboards are made out of a misplaced and ignorant jingoistic nativism, but rather because, all else being equal, I’d generally choose the item made in a western country (Canada, the United States, most of Europe) over one not made there under the assumption that the workers are probably treated better and make living wages. Taiwan is an industrialized country, so this probably doesn’t apply, but I notice the difference anyway. In addition, products made elsewhere usually cost less; I find it suggestive that, in this case, the opposite is true.

My goodness, to whom does the lovely voice in your your tube video belong?
Not to me, certainly!
You have really nice keyboard reviews!
I’d like to track your keyboard related articles but it’s not so easy because of the following problems:
* Sometimes you use the “keyboard” tag and other times the “keyboards” tag. I can create a Yahoo Pipe for aggregation but you should use only one of the tags consistently.
* The other problem is that the link of your tags point to wordpress.com and not to your blog, so it summarizes all wordpress.com blog tags. This can be transformed manually by the interested reader, like http://en.wordpress.com/tag/keyboards/ -> http://jseliger.com/tag/keyboards/ but it should out of the box.
that was a really good review. i want this keyboard for my office. i will pick one up soon. i do think it looks a bit ugly, but i had the old one before this and it was fine. (i spilled coffee on it and went back to a $10 logitech one)
and also skatter tech did a good review too. they have the full clear photo. u should see that too.
take image like that in future!
(sorry for bad English, I’m learning)
That’s a great review. As a keyboard junkie myself I really liked reading it.
There’s one thing you didn’t mention and I think should be pointed out. I recently purchased one of these keyboards and it took me a few hours to realize the problem.
With the new Model S that includes the media keys you have to give up the functionality of one of the two left-hand modifier keys (either the Windows or Alt key on PC or Option or Command key on Mac). You can switch which key in software by swapping the registry of the second key in from the left on the bottom row as that key is hardware mapped as the Fn key to activate the media functions of the keys marked in blue.
For me, on Macintosh, this was a total deal breaker. I kept thinking my system had a bug when I went to use an Option-Command induced shortcut and it wouldn’t work. I finally realized I had lost that functionality on the left-hand side and it was the keyboard’s fault. E-mailing support revealed there was no way to change this.
I went to Das Keyboard’s web site and a footnote in their FAQ about the new keyboard mentions this but unless you’re looking for it this is not obvious.
I don’t know if loosing left-hand Windows key function is a big deal for Windows users.
I’m sending the keyboard back. It’s a real shame too. I have an original Das Keyboard professional and was hoping for an improvement in the new model. I think these are nice looking keyboards with enhanced old school functionality for people who value typing.
This is a great review!
Your links for different terms are very convenient for me, especially the one to the Filco keyboard. I didn’t even know I could buy one in the U.S. for that kind of price.
I’d like to try cherry blue switches, and couldn’t decide between das and filco. With the availability of 87 keys and no letters on key caps in 2010, I’ll probably get one filco.
The reason for two USB plugs on the chord is that you can then have a full 1500ma available for what you plug in. I have had a few keyboard in the past with one USB plug and that meant that the total power for the USB hub was 1500ma – keyboard’s power draw. This prevented a few “high speed” USB thumb drives from working and a few multi format card readers.
Honestly, I applaud their forsight in having it use two USB plugs to provide ample power to USB devices connected to the keyboard.
I own two identical dasKeyboard Professionals and I cannot recommend them after using them for over two years. The reasons for my dissatisfaction:
1. I experienced a strange problem having to do with the ^ key/6 key which appeared to be a firmware or timing issue. The warranty swap process took too long and they did not have a good explanation for their slow service. The problem could have been verified in a minute if they had decided to design their service process in a customer-friendly way.
2. Today I am writing on a unit that fails to produce a b or v from time to time. Power-cycling the USB plug does not alleviate the problem.
