we bought the heater for a small space and are
very satisfied.
The construction of the fan is very robust and the case is due to the dimensions
rather inconspicuous. The fan operates audibly but not annoying.
As a safety feature is the bottom of the device installed a contact, the operation to
allows only the state and it switches off, this should tip over.
Overall, the fan for occasional use is recommended.
As a "duration-heater" the device mE but not out of the question, since the power
to low.
The reasonable value for money, so I can only recommend to buy.
