## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Heavy Duty
  

*by T***T on Reviewed in the United States on July 23, 2024*

It was very easy to put on the hitch.It encompasses the whole hitch and the lock fits snug so it would be hard to cut it off.  The lock has a special key that I would say is hard to pic. It’s thick steel and is powder coated I guess so it does not rust. Very satisfied with the purchase even though it was pricey but worth it.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I was skeptical
  

*by J***M on Reviewed in the United States on October 10, 2024*

The price made me concerned, but this is an excellent, well designed product and it even looks cool. Leaving my travel trailer with this in place makes me feel it is secure and that it would take more than an angle grinder to remove it.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Super Solid
  

*by Y***I on Reviewed in the United States on August 7, 2024*

Material is strong, fit my Ram hitch perfectly! No ones getting that thing off.
