I love this thing so much! I can't sleep without a fan and I often go to my girlfriend's parents' weekends where there isn't one. It fits under my clothes in the bottom of my backpack and is very light. It's also big enough to create a nice breeze, just enough for me to sleep on. It doesn't wobble, which is a bit of a shame, but I can usually tilt it well enough that this isn't a problem. It works well offline, but I don't know about the battery life as I didn't have to use the feature long enough to notice it. Overall it's great for what I needed - white noise and a gentle breeze to sleep away from home and my own fan running 24 hours a day, 7 days a week.
