The distance between the TV and my sofa from where I want to use the key board / mouse is about 15 ft. Will this work from 15 ft away ?

I have just now tested the keyboard and mouse at a measured 21 feet away from the front of my computer (the receiver is plugged into a USB port on the back of the computer) and both functioned correctly. I also checked performance on a book shelf 20 feet away with the keyboard and mouse at 90 degrees from the computer and out of line of site where the signal would have to also pass through ¾ inch of wood and neither functioned. Do note that all such RF (Radio Frequency) devices loose signal over distance. Hope this helped and enjoy you're your new keyboard and mouse.

I have a Samsung smart TV and will this be compatable? I take it that there is a receiver that you plug into the usb port and the TV will pick it up?

Yes it will work with a Samsung Smart TV. In fact I have Samsung Smart TV and it works perfectly. You use the same unifying USB transmitter that you would use on the computer. Just plug it into the USB port on the TV and it recognizes the USB transmitter automatically.

does it work with mac?

No! The package and Logitech's website do not mention MAC OS X, only Windows and Chrome. However, the M310 mouse does work with MAC OS X. The Logitech driver for their USB-based receiver is misleading because it mentions mouse and keyboard, but not the MK520 packaged with the mouse.

does it work with linux

I've tried this set on Windows 7, Linux Ubuntu 14.04, and Linux Mint 17.1. It definitely works great on windows. It seemed to work okay on Ubuntu Unity, but I was only using Ubuntu Unity for about a week before I switched to Linux Mint. In Linux mint I started noticing some keyboard lag. It could lag as much as 5 or 6 seconds at times which makes it impossible to use effectively. I ended up switching to a different keyboard.
