## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for doors with low clearance.
  

*by P***2 on Reviewed in the United States on March 19, 2017*

I have a low clearance under my door and this is perfect fit to stop air leaks.

### ⭐ 1.0 out of 5 stars







  
  
    Not wide enough
  

*by S***S on Reviewed in the United States on January 5, 2014*

The distance between the foam cores are too thin and couldn't close our windows.  Tried 2 windows for 30 minutes total...afraid we were putting too much pressure on the closing hardware trying to lock the window as the window did not close well enough. Took 2 people to try to install...and the 'stretch' material is basically useless unless you have 3 persons to install.. One inside holding, one outside holding and one closing the window...kinda hard on a second floor window...  Design flaw.  Don't frustrate uoursrpelf until they redesign.
