The fact you can tilt it up or down worked great for me.
Took this fan on a camping trip and used it at night to go to sleep.
Overall, this is very helpful for camping trips in the summer when a small breeze can help you get to sleep.
I have used them with batteries and am amazed how much cooling air they provide.
I highly recommend them for their portability.
Quit working after a few uses.
I received this fan the 1st of August 2017 and mid-october 2017 it has quit.
I can roll the batteries around a little bit and the fan runs at about a eight to quarter speed that's all I can get out of it.
After a week of use, the fan became very slow..no good.
The switch is so cheap when I slide it to the off position it doesn't stay and I have to take the batteries out to get it to turn off.
