- Reviewed in the United States on March 19, 2023This lock locks very easily on my shed. It rains alot here and yet this lock hasn't rusted or anything. It's very durable.
- Reviewed in the United States on September 30, 2024I hardly think Master padlocks need positive reviews: their reputation precedes them. The best.
- Reviewed in the United States on July 26, 2024This is a good choice for something you want to lock up with that does not have excessive value. More of a deterrent than anything. But works well, and is exactly what I wanted.
- Reviewed in the United States on July 11, 2024Wanted a heavy lock and needed a long shank to use on my 7000 lb.trailer.
- Reviewed in the United States on July 11, 2023Used to secure chain for my rv generator. Works fine
- Reviewed in the United States on February 7, 2025Pros:
- Sturdy long shackle
- It locks
Cons:
- SUPER EASY to pick. I am a novice, unlocked it in 10 minutes the first time, and now I can pick it in seconds.
- ZERO security measures like false gates, etc.
- The shackle can kinda get "stuck" making it hard to close / you gotta wiggle it.
- Reviewed in the United States on August 10, 2023Great product from a well named brand.
