Generally this is a very good package, The ability to charge both the keyboard and mouse by Micro USB is great. The keyboard came with a rubber cover (I'm not sure if its just for shipping) but the keyboard works well with it in place and saves the keyboard from some wear and tear.
Now for a few little quirks, which take some getting used to. The function keys are present on the keyboard but are only usable whilst pressing the Fn key on the left hand side of the keyboard. It would have been better if the function keys had been the main keypress and the audio controls been accessed via the Fn key. Also the \ is another key only accessible by pressing Fn and Z, another odd quirk that can be a pain when entering file system commands. It should also be noted that there is not ctrl key on the right hand side of the keyboard, only one on the left, again not a deal breaker unless you use the ctrl+enter command to send emails in GMail etc.
Overall this keyboard works well and is recognised easily by Win 7. The battery life so far seems good, the only reason I can't give this 5* is because of the slightly quirky layout (My own fault I should really have checked prior to ordering).
Worth the money paid as it was on a daily deal, and I would probably buy another one for my other PC should the existing one in use need retiring.
