Unfortunately, it did not manage even the second level support that all the functions on my 12 months aged Samsung LED TV can be used.
The buttons on the TV remote controls have different functions, in which menu you currently located, depending on where the TV.
However, the Harmony can maximally double occupancy for a key and it worked not always reliable.
In total I spent hours given me two weeks hence and also telephoned a lot with very nice Logitech Support.
Then I gave up.
For the idea of the feel and the service I would give 5 stars, but because they can not operate my TV, I give 2 stars.
Will I not soon try again.
