CONFIDENT–Takeaways after our first game

About Confident?, from BoardGameGeek:

CONFIDENT? is a highly entertaining family party game where you answer questions like "how many slices are there in a loaf of bread?". But, instead of giving exact answers, you guess with a RANGE! You only need to get the right answer in your range to win points so everyone can have a go, but the smaller your range compared to everyone else, the more you score! Are you CONFIDENT enough to win?
