### ⭐⭐⭐⭐ 







  
  
    Great coupler locks!
  

*by A***R on Reviewed in the United States on October 12, 2022*

These are perfect for trailer couplers. Very sturdy and easy to use.

### ⭐⭐⭐⭐ 







  
  
    Well made. Works smoothly for unlocking.
  

*by C***E on Reviewed in the United States on April 25, 2022*

The trailer receptacle that connects the trailer to the hitch has a lip under the hole that the bar fits in that gets in the way when trying to push the lock together. I have to push the handle back hard to lift it high enough to push the lock together to be able to lock it. If the lock had a slight bevel, it would be able to push together without the extra effort and work perfectly. I just received the lock so I can't yet attest to the durability.

### ⭐⭐⭐⭐⭐ 







  
  
    This is a nice sturdy lock
  

*by M***H on Reviewed in the United States on August 31, 2022*
