Product review (5 stars): Embarrassed to say I waited so long.
I wish I'd bought this sooner.  My dryer hasn't worked efficiently in years.  Although it occurred to me that I need the vent that goes up through the roof to be professionally cleaned or possibly replaced, the electricity to keep running the dryer seemed cheaper and easier.

Items that used to take multiple cycles to dry now dry in 20 minutes.  I'm not exaggerating, hence the source of my embarrassment.  A grown woman should have known it shouldn't take 3 hours to dry a load of clothes, even if there were jeans and towels.  Also the lint is being collected more efficiently in the dryer filter so I have less lint on my clothes.  The amount of lint on this indoor filter is not unreasonable and it isn't difficult to dump it out after each laundry day.  I'm dumping mine into my compost bin outside.

I can understand why this item might not work for everyone.  Venting hot damp air into a living space in the summer is a terrible idea. But venting warm damp air into a home in the desert in the winter is not only going to make my home more comfortable, it's going to save on my heating bill.  My laundry room is just off my kitchen and because of it's location I can vent my dryer into the garage, into the main living space or to the outside in shoulder seasons.  By next summer I will probably have saved enough money to pay to have the vent pipe replaced and even when I do I am still going to use this item in the winter.
