Product review (5 stars): Better deal than the Heartland dryer vent
This is the 2nd Lambro dryer vent I've purchased.  It is every bit as good as the Heartland 21000 dryer vent that sells for $37.99 (nearly 2x the cost of the Lambro), which I have also purchased previously.  The only possible disadvantage of the Lambro is the little catch that holds to top in place, which seems a little weak.  It does exactly what it is designed for, keeps critters from getting in and lets the hot, humid dryer exhaust out.
