Review on 🌀 Whirlpool 4396037RP Vent Periscope - Optimal 0-to-18 Inch Extension for Improved Airflow by Casey Oliver

I am pleased to repeat the satisfaction of previous satisfied reviewers. After the product has been cut (easily with metal scissors) and wrapped with tape (silver tape) to prevent air leakage and lint, the product easily fits onto the dryer outlet and onto the wall outlet. I thoroughly cleaned the vent up to the roof and also vacuumed the dryer vent (which I did regularly). I opened the front bottom panel of the dryer to vacuum out any excess lint that had accumulated there. It only took me one cycle to dry my next load of clothes. The dryer works much more efficiently than I expected. Since then I've dried many loads with the same efficiency. Very happy when I find a product that works as advertised!
