This keyboard is a very descent keyboard for its price range and is perfect for the everyday user. It's comfortable to use, sleek, light weight, and comes with a Logitech Unifying receiver. If you've already got a Logitech mouse with a Unifying receiver then this is the product for you. But if you want a keyboard and mice combo then I suggest looking at the MK260 which is pretty much the same as the K270 except it comes with a mouse.
This keyboard is extremely light weight which means its light to carry around and also light to use on your lap. The wireless range is perfect and does not suffer from any lag under normal usage. It also features an on/off switch located above the numeric keypad which is really handy. But as well as the on/off button this keyboard also features auto standby and goes on standby after a certain period of time where it is not in use.
Overall this is an exceptional keyboard for its price range and its intended use. With extremely sturdy rubber feet and great functionality and features I would definitely recommend this to a friend and you!
