I tested several wireless keyboards sold less than 40 (maximum budget for this type of product in my case), the Logitech MK270 and Microsoft All in One with integrated touchpad. I have them all returned due to an obvious lack of comfort, resulting in too many typos. For cons, I kept this Logitech MK520 because it works perfectly (correct finish, good typing comfort, large keyboard, very good wireless connection, key lock light capitalized, multimedia keys, on-off button, consumption reduced, and 2 years warranty Logitech). And with the Unifying compatibility, I could connect the keyboard to the USB dongle my Logitech trackball, without adding extra dongle. And you can connect up to 6 Logitech devices (useful when only has 2 USB ports). So, I have not tested the (small) mouse, as I much prefer my trackball. Note that some USB ports 3 seem sometimes cause connection problems, with random cuts and delay taking into account of the seizure. Change USB port can be enough to solve the problem (prefer USB 2 if possible). In summary, at this price I do not see better on the market today. I recommend!
