I won when it was in previews, and I got the second row of the balcony (B10 and B12, if you want to be precise). It felt a little far back, but it did offer a great view of the whole stage.
I saw the show from row D of the balcony and thought it was a great seat. Could see all facial expressions quite easily. I never felt removed from the action. I wouldn’t pay $100s to sit up there but for $30-$60, it is perfectly fine.
