“Product well made and exactly as described. Excellent value buying directly compared to other sellers (Amazon/eBay/etc.) and supporting this company, especially when buying multiple units and paying one postage. Recommended.”
“Excellent product! Shuts off cold air from outside with the slide of the switch, brilliant filter can see it has already caught dust and stopped it from coming inside. My room is a lot warmer thanks to these! They are pleasing to the eye and a fantastic modern touch to my home! So glad I found these and purchased them. They are, without a doubt a Revolutionary idea in venting!”
