Works perfectly as a replacement for my TV, Argosy player, and DVD (all in one system we have), but doesn't seem to work with SKY, but in all honesty I'm prefectly happy now having 2 remotes (SKY and Harmony).
The kids know how to use the SKY remote with their eyes closed, so seems to make sense to leave that one as it is.
So all in all, very happy with the outcome..
