Product review (4 stars): A bit noisy even at low speed.
Nice design if compact space is a factor, but with the two motors it is noisy and creates a resonance frequency sound in cabinets and enclosed area. This is just in the lowest speed. I bought it because of the slim design and small footprint under the cabinet. I think the two motor design is for commercial use. I'm planning to disable one motor, Other than that it looks pretty.
