## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Worked great for my portable ac exhaust
  

*by B***N on Reviewed in the United States on August 6, 2022*

Fit right over the hose. Cut to length with scissors.

### ⭐⭐⭐⭐⭐ 







  
  
    Ahhh, so worth it.
  

*by J***S on Reviewed in the United States on August 12, 2017*

Purchased a portable air conditioner for my bedroom; found that the exhaust hose was hot to the touch and emitting heat which defeated the purpose of cooling the room so I purchased this 6" diameter duct sleeve.  After running the hose through it, I secured the ends with 24" zip ties.  My room definitely gets cooler quicker after installing this sleeve, noticeably so; a bit bulky but very happy with the results.

### ⭐⭐ 







  
  
    strange smell
  

*by E***B on Reviewed in the United States on June 24, 2019*

I've installed this product on my portable air conditioner exhaust hose and it is doing a good job of insulating it and stopping the heat from radiating from the hose, but the strange chemical smell is totally unacceptable and can be smelled all over the room.  There's no way I can spend the rest of the summer breathing in whatever that is.  Out it goes.
