I just got this fan and it's working damn well so far. The fan has 4 settings and delivers plenty of air when you need it. As you will see from the photos, everything is there that I have never liked. I don't understand why they make the instructions so small. Anyway it's super quiet, you can see in the video it's super quiet. Not sure how long the battery will last, but it runs at full power over USB. USB also charges a rechargeable battery, which is really nice - never having to buy batteries is great. I haven't tried the scent but this piece fits the back very well and I can see how it would work. Either way, a great quiet little fan for a desk or whatever.
