This ultra slim keyboard fits easily in my backpack. I was afraid it would break but so far it has proven strong. Typing on this keyboard is mostly comfortable. The keys register well and the clicks are not very loud, so it shouldn't bother others. Real estate is scarce when you have big hands like me. I can type fairly comfortably, but my knuckles bump against each other from time to time. The communication is good. There is a delay when both my Kindle 7 and the keyboard sit idle for a while, but it's a few seconds at best. The keyboard isn't impressive, but it does a great job, which is to be expected of it at a good price.
