Master has always been the best choice. Everything works as expected

This is a good lock. Easy to access. However, over time it is harder to get the lock section on the post and locked because of dirt and debris.

Unlike a similar well-reviewed lock, this one fit my car much better because the rubber around the lock mechanism is much smaller. This doesn't conflict with my plastic bumper, and seems quite sturdy. I'm happy.

Perfect design. This is the 4th pin lock that I have purchased over the years and the design is the best by far. By having the keyway facing out instead of off of the end is much easier to operate. When the keyway is off of the end it is cumbersome to lock as you really need a third hand. The key is also more robust than a typical key of this style.

The locking device insures that the expensive three ball devise will not be stolen

Only lock I could find that fits in the 2024 tesla model y hitch due to the placement of the electrical outlet. Just barely fits and works great. The appearance is excellent as you don't really notice it.Probably not super durable as it's a masterlock and a cheap one but in this case it's the best I can get.Lock is a little finicky but five star for solving my problem.
