Product review (5 stars): Worth it
Have only had for two months or so but it has made a big change in the temperature of my laundry room. We have a very short vent to the outside and my tile laundry room floor was freezing due to all the cold air that the louvered vent was allowing to come in. This has put a stop to that problem. Easy to remove the old vent and install this with just 6 screws.
