Product review (1 stars): Wrong size
This flexible hose is pictured as an add on with the Honeywell portable air conditioner.  The problem is the hose that fits the machine and window attachment is 5" in diameter this is 4". It is also thinner and has a very strong plastic smell.
Don't make the same mistake I did and order it before you know you need it.  Returning it where I live I have to drive over 20 miles to a free drop off, or pay half of my refund and take it to a to a UPS store less than a mile from my house.  Or pay more than the hose and clamps and have UPS pick it up at my home.
