Never thought such a small fan could create such a strong wind. The speed at the lowest level is impressive, and at the medium level there is almost a gust of wind. Also, with this kind of wind you would expect it to be noisy, but it's actually a lot quieter than I thought it would be. The ability to charge it in advance makes it ideal for travel, emergencies, camping, etc. Its light weight also allows you to pack or carry it anywhere without taking up much space.
