Product review (5 stars): This thing rocks
I do have a long run to vent my dryer, about 23 ft. but it was within spec. Have had this dryer about 6 years, another 6 years before that. I have always, always, always, had to add extra time to the cycle to get a load with heavy stuff, towels, jeans, etc dry. When it would get particularly bad I'd clean the duct, which helped some. This last time I was searching on duct cleaners came across the subject of these booster fans. Looked at the other models, but because of a really tight & peculiar vent run would have been a major pain to install. Actually even with a simple run most of these are a pain to install. Must be so many feet from the dryer, so many feet from the exhaust, oriented in this particular position, hard wired, etc. Rolled the dice and got this one - super easy to install, sits on the floor about 2 feet behind the dryer (in my case.) Plugs into a regular outlet. It's quiet, starts & stops right on the money with the dryer. And finally, after 12 years in this house I can dry a full load of clothes in only 40 minutes! Kudos to this company for coming up with such a simple, innovative solution to this problem.
