The Logitech Harmony 880 allowed me to go from 3 remotes to one easy to use system. The initial set up can take awhile depending on how many systems you are incorporating, however it is very straight forward and easy to understand. Once the control is set up, it is amazingly simple to use. My 10 year old granddaughter navigates through games, DVD's and the TV with no problems whatsoever..
