Review: Quality and it works perfect - Worked perfect I had gaps around my dryer vent this sealed it off and made it look nice and neat
Review: Great quality, and benefits - This purchase was more than 5 ⭐️⭐️⭐️⭐️⭐️⭐️ it was extremely easy to install, the fit was perfect for my wall, the material is heavy duty, and the clean finish that it provided for my dryer was worth every penny! I don’t have any excessive heat coming from or around my dryer hose. It’s super clean looking, not flimsy or cheap. It was very easy to attach and apply the hose. It just looks so much more sturdier that just having your dryer hose attached to the wall. It surely does stop any escaping heat when drying. Worth buying and should I need another one, I will buy again!
