Summary: Purchased this keyboard to use away from my desk in meeting (I like the fact that I can roll it up and carry it in my bag with my laptop and it doesn't take up any room), but if you're used to typing fast this keyboard is not for you, the keys are not sensitive enough for a fast and light touch, it's better for someone who has the patients to type hard and slow.
Summary: I'm reading through the comments from the beginning, which is more than 4 years ago. I think the manufacturer made some improvements through the years, one I see that they made the 'faces' of the keys slightly more rigid, which helps somewhat. Still make no mistake about it: This is a specialty product, which could be a godsend under certain circumstances, but it's not without some distinct and hard trade-offs.
Summary: This is an okay keyboard for what it is. I use it mainly for my tablet but it's an okay alternative for a computer. I would recommend a solid keyboard for a stationary computer, but for on the go use, it's pretty good. It'll survive harsh weather and can be rolled up for small storage. Overall it's a moderate keyboard and isn't meant for typing fast.
Summary: I bought this keyboard for our rock climbing gym because of all the chalk dust. It works well in that it is washable and dust resent. However, I do not like the way it types. What is it is hard to type on. It is easy to think that I hit a key but didn't or used the shift key but didn't. I spend too much time retyping mistakes made on this keyboard that I not make on a regular keyboard!
Summary: This keyboard is just what I needed--portable, durable, plug-n-play concept. And because I'm a quasi hunt-n-peck typist, I haven't noticed if the keyboard has difficulty responding to a lighter touch.
