does the job


I'd recommend it if you need portable external keyboard.

Does the job, helps me when my small laptop keyboard fails, and fits into my bag with the small computer. I travel the world in rough conditions, and this holds up

Takes some getting used to to type accurately, but once you learn to type more like playing the piano (finger strikes more vertical, and percussive), it types just fine. When it's been rolled up, the initial typing has inaccuracies until the keyboard...

very destructible


Don't waste your money.

Waterproof, small, rolls up, flexible

I have had this keyboard for 2 weeks, used it maybe 3 or 4 times, now the "a" key is stuck on and constantly typing "a"s, which renders it completely useless ; Even when it did work, it was hard to use since its keys are mushy and smaller than a normal...

Great idea but performance is poor


Bought the keyboard to use with my netbook to use a full size keyboard rather than the smallish netbook keyboard. Problem is that the keyboard is stiff and unresponsive so that letters and spaces I type don't always register which means lots of typos...

Flexable, quiet

Zero key sticks, even though rubber part is not stuck to electronics. Don't buy this. It's a piece of garbage

Ok, pros and cons


The one sent me isn't the exact one shown here. It has the control unit on the left side instead of the top. I actually like it better because it rolls up easier. Other than that i think it is the same 85-key layout.

Spill resistant and super quiet. Comes with ps/2 adapter. Rolls up nicely and stores easily

Keys don't always work when pressed. You really have to check to see what you're typing after every word or so. The space bar is really bad about it. Don't use for gaming or typing in word. Its more for light use or portability

Not as good as it used to be


I've owned two of these. The first I got maybe 2-2.5 years ago (a previous model) for my home computer. It was odd at first, but had very smooth typing. Loved it. I got this model about a year ago at work. Much stiffer keys, making typing more...

Silicone, easily to clean, durable

Stiff keys and some goofy key placements

Odd for a touch typer, great for kids


Got this for my son's computer as my youngest (2 years) kept removing the keys from his previous keyboard. When I first unpacked it, he spent nearly an hour trying to figure out how to remove the keys. Didn't work out for him. I recommend this for...

It's indestructible, my youngest son can't remove the keys from it (read below), my oldest son can pour whatever he wants on it and I can just run it under some water to clean it off, cheap when compared to the other indestructible keyboards

For myself, being a touch-typer and very used to normal-feeling keyboards, I find it kind of a nuisance to type on this thing. My son hasn't started learning typing, though, so he's perfectly okay with it. I wouldn't think of starting my son with...

Latest models are throw-aways


The CTRL key has been a lower right, bottom-most standard for decades, but GrandTec finally some how got it wrong. The rubber is way too stiff to type accurately or at all the o of the control button. What are they thinking?

I've been using The FLX series GrandTec boards for almost a decade now, and have even converted my office to use them for silent productivity. The original models were quick to adapt to and had volume controls in-place of three useless nubs. The second...

With the latest reversion, however, GrandTec has turned a classic into a complete dud. Key presses simply do not register without full and forceful contact. It has taken a 90+ WPM user down to less than 30 thanks to constant corrections. The most...

It is so easy to store and will not get damaged from pressure or falls. I tried to rip this thing with my hands and it still works! It is very easy to clean and any accidental spills will not short out this keyboard

The placement of the buttons on this keyboard is unorthodox. There is more than one shift and space button. It takes a while to get used to it and the buttons can move from side to side instead of bouncing up and down so be wary

Finaly broke one


Because of the price, i got this for my wife as a keyboard for her to use, she spills everything on them and i was tired of having to replace normal keyboards. I finially had to order a new one after almost 7 years of using it. I can tell you she will...

belive it or not, the only con i've ever heard is that it doesn't come in other colors

Product Specifications

The Virtually Indestructible Keyboard, a silicon-based flexible computer keyboard, features a unique combination of durability and soft, comfortable feel. The washable, "roll-able" keyboard has been called "the best thing to happen to typing since the backspace key." The VIK combines state-of-the-art technology with practical design to produce the perfect keyboard. The unique layout offers quick, reflexive typing action that is not only silent, but also more comfortable than standard hard plastic keyboards. The "flat-out" design eliminates negative-angle wrist stress, an unfortunate and impractical holdover from the archaic days of manual typewriters. The silicon-based material is impervious to most anything including water, coffee and cleaning solutions. From the classroom to the factory floor, the Virtually Indestructible Keyboard is poised to revolutionize how the world types.
