Product review (5 stars): Most of the time we run it on low or medium The lights are adequate and definitely brighter than the single light in our original hood We like the rounded corners
This replaced our ventless hood - our kitchen is all electric and codes, as in many states, allow ventless range hoods for all electric kitchens.  However, we want a hood vented to the outside. Contractor installed the hood with no problems. The ducting was a little more challenging and that is not the fault of the hood but ratherthe placement of beams with respect to the cooking surface.
We were not concerned about vents for make up air. This is not a whole house attic fan by any means although it does have reasonably strong suction on high. If we run it on high, we open a window. That is just common sense anyway if one has created a smokey or smelly mess in the kitchen.  Most of the time we run it on low or medium
The lights are adequate and definitely brighter than the single light in our original hood
We like the rounded corners.  Many hoods, including our original one, have sharp corners, which can be hazardous.
We have had it for several months and are very happy with it.
