Summary: I have one that I purchased like 10+ years ago (purchased at CompUSA). The letters will eventually wear off on the most used keys. I can say that many reviewers complained they had to pound on the keys to get them to work but I've noticed with the one I had for 10+ years, you have to "break it in".
Summary: Only thirty day warrantee and now I know why..... I used it four times in six months and some keys already do not work. Many were difficult to get to respond from the beginning but I, stupidly, assumed that would correct with use. I only carried it in my laptop case and did no abuse.
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,...
Summary: This works, but you're gonna need a good spell/error checker as the keystrokes are inconsistent. It does work, just not as well as a $10 real keyboard. On the good side, it rolls up fairly compact so if you're hiking with your computer (why?) it's good.
Summary: I had finals coming up and couldn't afford a new laptop, or to borrow one. The keyboard of my laptop had 3 letters that stopped working, A, T and C. All of which I'm sure I would have needed for my exams so I bought this.
Summary: I have used this keyboard for a few days and the biggest issue that I find is the "space bar" (actually two separate keys). On my keyboard unless you depress either one of the keys "firmly in the centre" they do not register.
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.
Summary: I travel frequently for work and purchased this and an ergonomic tray to stop myself from slumping over my laptop. Some other reviewers talked about the stickiness of some keys on this keyboard and I agree with that. I find myself having to hit keys harder than I would on a normal keyboard.
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.
