I use this in the office on my desk, as our ceilings are 25' high, and sometimes the air at desk level gets a little hot/stale. This keeps the air stirred around me, keeping me cool and productive. The two settings pretty much cover most needs - I think the company has erred to the side of simplicity. And it's plug and play. Not much that needs explaining. All in all it's a good little unit, perfect for it's use.
