Product review (4 stars): Appears to exhaust smoke well....
This unit was considerably less expensive than any I saw on Amazon, but I'm pretty happy with it. Certainly no louder than my original unit, and seems to be more efficient. A little trouble installing, but I think that might have been more about operator error. Can't speak for durability yet, as I've had in installed for about 6 weeks. Looks more expensive than it was, and I would buy this product again.
