Product review (4 stars): Works as described- you may need help with vinyl siding install
Although quite cumbersome, this product works very well so far. I had my contractor friend take down the vinyl siding for me to install this-he used a special tool and I had never removed vinyl before and did not want to wreck it. No cold air coming in through my dryer in Maine (January). Normally the clothes are very cold if left in the dryer after a cycle but not anymore. No drafts in my bathroom anymore (also washer/dryer room). I did not paint this product yet although I will take the round top piece in this week to do so, and will paint the elbow piece that is attached to the house in the spring. As for the heat savings I'm sure there will be some, but as for 10% savings- we will see about that. I think this product will look less cumbersome when painted to match my vinyl siding. If anything changes in my approval of this product, expect an update!
