This little fan is incredible! I purchased it for a trip to Disney World in mid June. I had the fan on high most of the time and it still lasted for 10 hrs. Easy to carry and very lightweight. I had several people ask me about the fan because they could feel the air movement. One family had purchased the fans that you wear around your neck and said that it didn’t work. They said that this fan was much more efficient. I love this fan and highly recommended it.
