## Customer Reviews

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Good product but intentionally missing screws
  

*by E***M on Reviewed in the United States on April 16, 2020*

Marking this a 3 because it did not include the screws which makes it extremely frustrating to go to a hardware store and have them try and match the proper fit.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Doesn't come with screws otherwise it would be 5 stars ...
  

*by Z***M on Reviewed in the United States on March 4, 2018*

Doesn't come with screws otherwise it would be 5 stars. No information as to what size screw it needs either.

### ⭐⭐ 2.0 out of 5 stars







  
  
    NO SCREWS
  

*by C***S on Reviewed in the United States on October 29, 2019*

NO SCREWS it is well made I would give it 5 stars if it came with the screws to attach it.
