I really like the product, it fully meets my expectations.
I took this baby to blow my face on a hot day. It copes with its task with a bang at the weakest speed.
We took it on vacation, in the car in the back seat it helps a lot, if the battery runs out, a portable battery will help out.
Pros
The presence of a battery.
Good power for its size.
Quiet (more precisely, not a distracting rustling)
