## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    appears tough as the titanic
  

*by M***L on Reviewed in the United States on 7 October 2023*

very heavy guage, even an angle grinder going to take some time to cut this off in my opinion, i think i can relax shopping in a store, bike still there when i return, the lock and keys will resist corrosion, very smooth operation now while its new, its wide enough and very secure for a few hours if you get it around a steel sign pole,far betterthan any chain or cable alone, this would be great to secure a property gate to prevent the intire gate removed and stolen, im recommending it more than worth the money

### ⭐⭐⭐ 







  
  
    not the size advertized
  

*by Y***L on Reviewed in Canada on 18 June 2022*

not the size advertized-maximum 14mm, somme loose in deadlock-too much for my taste, I guess the real thing is 120$ and more

### ⭐⭐⭐⭐ 







  
    Muy bueno el candado 12mm
  
  

*by O***O on Reviewed in Mexico on 18 April 2022*

Me gusta el grosor de su grillete y que tiene su porta candado para amarrarlo al cuadro, pero lo que considero inutil es el flex en Mexico solo generan confianza, gran numero de robos es porque se aseguraron con estos flex asi que ahora me toca buscar una cadena de acero cementado para sustituir ese flex.
