This keyboard is comfortable to use and has a number of useful shortcut keys including some customisable keys which can be used to launch apps or webpages. I particularly find that I like having the shortcut key to the calculator which comes on a number of microsoft keyboards as well as volume and a/v controls (play/pause, skip etc). There are few downsides to this product in my opinion - - The receiver is a large USB stick instead of a one of the small micro or nano receivers and this is a big draw back for me if you are using with a laptop. - The mouse is a full large size mouse, which nowadays I find a bit uncomfortable as most people use slimmer smaller mice these days, personally, I would have preferred a smaller mouse that is not as bulky to carry or hold. - Lastly, I haven't found that their "BlueTrack" technology has been any better than their standard optical tracking and in fact, in one situation I found it gave me problems where the standard cheaper set did not.
