I gave this as a gift to my sister and she was impatient and did open them all at once. She liked the variety of dice. She said they were all good quality and nice mix of the different sides dice. She has not told me how her game sessions have gone, but they appear to roll well, with none rolling weighted to a side. Even the ones with embedded items are balanced well.
I ordered this for myself and as a birthday gift to my roommate! Loved the dice. Theyre lovely and I admit I was SUPER impatient. The one thing I'd say is the box struggled a bit. During shipping, the day dividers gave out and the dice didn't stay in place. Took 3 day boxes to get any dice out! Most slipped and slid around. Still, loved it since my impatient self ended up going for all of it at once within a week!
