Depends which part:
Ambi Selectors are great. I'm right-handed, and still like the BAD-ASS setup on stuff... I wouldn't hesitate to have these on every lower.
Ambi Magazine release - the Norgon is my favorite, but it still can get caught up on gear and drop magazines; even the others are just OK. I've found that I can just as easily use the right hand thumb to pull magazines if I'm driving the gun from that side, so I'd argue these only have utility for true lefties. The KAC flavors of this options are a touch nicer about getting caught on stuff, but those are pricy and incomplete on the next part...
Ambi Bolt Catch - these are the really variable ones, the KAC just drops the bolt but won't hold it open, and the AX556 is a pretty attractive option. Since I keep stubbornly running BAD levers, it doesn't actually change much for me, so I run the Noveske Flared lowers, throw ambi selectors on it, and I'm utterly happy with this setup for everything I need, so much so that I run these instead of my pair of KAC SR15 lowers.
