Jessica, some of mine will eat them, others won't. I don't offer them to the geckos that are under 40-45 grams or so though. It might be okay, but I primarily use the pinkies for the leos that are breeding. One of my breeder males doesn't want anything to do with insects when he's in with a female, but he can't pass up a pinky mouse!
With the dragons, I'll give a pinky to pretty much any dragon over 75 grams. Recently I switched to giving the dragons frozen-thawed pinkies only off the end of tongs, and that seems to be going well. They make less mess than the live ones when they eat them.
