+ Super Value
+ Unobtrusive design
+ Much sturdy plastic, safer stand seems to last
+ Relatively simple self-assembly, despite some confusing instructions
+ Quiet! The (lowest level 1) fan noise does not bother while working.
+ Lowest level 1 (of 4) perfectly adequate
- There could be a lower level than 1, as I sometimes but "fröstle" VA or if I only need fresh air for a quick bike ride
- Higher speed settings 2-4 promote the "paperless office"
