### ⭐⭐⭐ 







  
  
    Wouldn’t stick
  

*by C***R on Reviewed in the United States on March 15, 2023*

It wouldn’t stick to the surface. Disappointing.

### ⭐⭐⭐⭐⭐ 







  
  
    Easy and works
  

*by A***M on Reviewed in the United States on December 27, 2022*

I have installed window plastic every year on my patio door.  This product is one of the best.  The adhesive stayed on the wall!  In years past, even with cleaning, that hasn’t been the case.  I can tell an immediate difference after installing this in draft reduction.

### ⭐⭐⭐ 







  
  
    Doesn't shrink, fragile when cutting
  

*by P***F on Reviewed in the United States on November 23, 2022*

The plastic portion was difficult to cut and is quite fragile; I couldn't cut it on a straight line, it shredded into small pieces as I cut it. It also didn't shrink much. The product I used last year (3M? but couldn't find it this year) was so much easier to use and the hair dryer shrank it perfectly so you could hardly see it. I think it will work to stop drafts anyway.
