Product review (1 stars): Don't buy this exhaust hood, unless you like unpleasant surprises.
The blower only works on 1 speed. The clock is set in military time and there is no way to change it. Only the light button functions properly.

We did not follow through on a claim as it would cost another $500 to uninstall this and replace it with a new one, resulting in $1k labor for the exhaust system.
