Turbo mode only 15 minutes
This is a strong range hood. I would have given five stars, but give four because the turbo mode only lasts 15 minutes. After 15 minutes the speed goes down to the default speed, which is the mid-speed. I would hope future versions would have more speed options. (I see that the latest 36 inch hoods they offer have four speeds. I would hope that the new modes speeds maintain the speed for however long one wants.
Also, I would prefer to have the automatic shut off timer to be longer. I have an old Accela with four speeds, and the timed shut off is 15 minutes. A longer option of 10 or 15 minutes would be nice.
