My son set the harmony Link up with my DH's theater system Jon set up for him. Very easy to use. it's not the HL that is the learning rev. it's setting up all the equipment correctly. That takes time. Jon set it up to work thru the BlueRay and stereo surround. It all works great, and have 7 items on HL. The only thing I have found that throws in a hijinks.is when DH is watching Netflix via the BlueRay. If he is thru at the Netflix point and doesn't go go to the watch TV menu first before turning off the system, it causes problems then with turning the sequencing of items. MI had to resync the HL ap on the iPad before I figured that out. Simple fix. But I love this system. I can finally see what to hit and easy to maneuver, and the Mister couldn't be happier. He, the mechanical genius, is computer challenged. he's learning more to do with his iPad because of it. Mof course, I got him his own.....didn't want him to touch mine and cause problems (GRIN)
