## Customer Reviews

### ⭐⭐⭐ 







  
  
    To big for inside garage door.
  

*by M***Z on Reviewed in the United States on November 2, 2022*

Like but wishing it for inside door. Bought for door that was broken into and helps hold doorknob in place, plus able to open/close door easier. Not sure how I am going to fix problem, but okay for quick fix. It’s to wide for door.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect
  

*by T***. on Reviewed in the United States on September 3, 2020*

After accidentally cutting the door hole a little off I decided to order this. It fixed my mistake and made it look perfect. Can't complain. The install was extremely easy as well with decent instructions.

### ⭐⭐⭐ 







  
  
    Missing parts
  

*by R***O on Reviewed in the United States on April 4, 2018*

Product itself was okay, but the sealed bag of hardware had only half the screws. I don't know if the bag was short or if there was supposed to be a second bag, but I will have to go buy screws to secure the plate. Also, the metal dimpled a bit from the pressure of the Schlage deadbolt being tightened to the door. so I wish it was a heavier gauge.
