Product review (5 stars): The Heartland's great. The Lambro is great. You won't go wrong with either one.
I bought both the Heartland and Lambro dryer vents. They are virtually the same. I didn't see any weaknesses in either one, and I would be happy to have either installed at my home. The Lambro arrived first so it got the nod. See the rest of the review, which is mostly specific to the Lambro, here:
