This is a an absolute great product that does what it is designed to do and that is to seal the hot exhaust air from a portable AC unit hose to vent it outside, yes like some reviews I saw before I purchased this had said it is tight to wrap around the hose but in my opinion that is what also has made it an excellent product too! We worked to get it wrapped for sure but now it totally blocks all heated air exiting that hose and has none escaping into the air conditioned room! Well worth it for sure, just realize you will "work" toe get it wrapped but it does fit, just very snugly which when done turns it into a product that does what it's supposed to do! Thanks Guys
