We loved this costume and so did our daughter. She just had to be a minion, so after not finding any minion costumes in our stores we decided to try Amazon. This costume is so much cuter in person, and after adding batteries they actually lasted so much longer than I expected. I carried extra batteries with us just in case but never even needed them. The only downsides we found is the visibility is a bit hard so I would recommend them not walking alone without guidance and she got so cold with the fan blowing the cool air in the costume. So definitely wear something warm underneath.
