Product review (4 stars): Good price. Plenty of airflow.
Good price. Only one fan whereas more expense models tend to have two. However, it provides plenty of airflow for my vent which is directly on the wall. The flowrate will go down if you have a long, obstructed vent. I would, however, much rather have LEDs than halogen bulbs.

I bought this to replace an over-range microwave that died. Those types of microwaves apparently die all the time because steam from the range gets into the electronics. This solution is more cost effective and more functional if you can sacrifice a little counter space for a countertop microwave.
