Product review (3 stars): Decent Economy Stove Hood
This appears to be a decent quality stove hood. I had to return the one I received because it had only a rectangular cut-out for venting. The picture appears to be circular. I could have gotten an adapter and re-cut my existing duct to accommodate this but, no. I've purchased these type hoods before and they usually have a precut punch-out with sleeve for circular ducts.

Anyway, for the price, this is a good choice for a low budget stove hood. Again, FYI: this accommodates rectangular top-venting ducts.
