Summary: Aside from novelty roll-up and membrane keyboards, this is the worst keyboard I have ever owned. The feel of the keys is OK, but the plastic is very thin. I've had this keyboard a few months now, and it has since stopped working. About a month after owning, one of the plastic legs snapped off. Not much more to say, I don't think it's worth paying $10 pr 15 for something that you will have to replace a few months down the road.
Summary: I had to press & to get *, the parenthesis were switched, the @ symbol was nowhere to be found on the keyboard -- when I pressed SHIFT, 2 (where you normally go to get the @), I get the ^ sign. There were a bunch more errors. No, there was no function key or Alt or Ctrl or shift key pressed. I tried every which way to see if I was doing something wrong. Plain and simple, completely haywire. One star for functionality, two stars for feel.
Summary: I purchased this keyboard in late January. It's now mid/late april and the windows key and 'r' key no longer work. It's not quite seen 2 months of use. Granted this is a cheap keyboard, but I think you should get at least 6 months out of it! Regardless, I will be requesting or purchasing a new one to replace it. Key action is rather nice and makes typing easier than the laptop style keyboards provided from my employer. Thank god it's so cheap!!
Summary: I purchased this keyboard to replace one damaged by a spill and noted the amount of liquid the keyboard was to resist. The keyboard received a sprinkling from my spraying window cleaner near it and even after two days of drying out, the lights came on, but none of the keys worked. I have now ordered a new keyboard (almost same price) that says it is SPILL-PROOF and have my fingers crossed.
Summary: Usually, one should have used a product before reviewing it. But in this case I can tell from the pictures that this board is not for me. That is because the Function keys do not align vertically with their respective Number keys. Here's how it works, Logitech: the F1 key goes directly above the 1 key. The F10 key goes directly over the 10 key. Ok? This brings the whole north end of the board into harmony, making finding things a breeze.
Summary: Don't get me wrong, this is a good keyboard. But the description of it is over rated when it comes to how quite it is. I have a computer center that sits in a hall way area adjacent to my living room where I am using this keyboard. My wife sits about 20 feet away while watching TV and she can easily hear me typing, even when the TV is on. How do I know this? Because my wife constantly ask me what I am writing.
Summary: I use keyboards much of each day and find this one the most sensitive to the slightest irregular touch which causes additional characters from adjoining keys. It has a very short stroke that I am not used to. A previous user liked the light touch so this may be a personal preference. The keyboard has a coating that is slippery also--very unusiual. Otherwise a good price, good quality, very easy to read and probably durable key images and otherwise high quality.
Summary: I don't know what the majority of people reviewing this keyboard were smoking but this keyboard is definitely not quiet. I can't believe Logitech describes this keyboard as "whisper-quiet". Where exactly is this level of racket "whisper quiet"? In a factory with grinding machinery? At a heavy metal concert? Definitely not in an environment where people are actually trying to concentrate and work while keeping noisy distractions to a minimum.
Summary: The keys are flat and squished too closely like a laptop, something I wanted to avoid. It's slippery like ice and easy to mistakes on, especially if you type fast (100+ wpm) Lastly, this keyboard would "shut off" for NO reason. Replugging doesn't work, you have to RESTART! It's super affordable, but you get what you pay for.
