After unpacking, first disappointment: Attention, there is no upper grid! This is a solid part contrary to what one might think seeing the photo.
Second disappointment at startup: very noisy but mostly very little heat! It is necessary to be at least one meter to feel a little bit of heat ... if it is rather cold ...
Finally, the small LED in the central nozzle ... what interest? Give an "impression" of heater in my opinion ...
In any event, I do not succeed to heat a part of the passenger or to unfreeze my windshield with this gadget ...
However, I said that the delivery was perfect, product well packaged and express delivery. It is the only "+", sorry.
