The buttons were a bit fiddly to program but after a few tries it worked. One of the 5 star reviews has revised programming instructions that may help. I have replaced two remote controls with this unit, HDTV tuner and TV on/off function. The output of this remote was stronger than the tuner remote and at least as powerful as the TV remote. Removed 4-5 stars but overall 4 star rating was due to unanswered question to seller. Finally it was answered by another user.
