High Security Padlock Single - Military Grade Ideal for Storage Sheds, Toolboxes, Worksite, Gym Locker Lock, Portable Door Lock, Bolt Cutter Proof, Steel Alloy Design

I've been using these locks for a bit now and they have performed well. Some users have reported difficulties with opening and even broken keys. It is true that these locks don't open as easily as a standard padlock but that's kind of the point. Isn't it?To open you turn the key clockwise about a quarter turn or so. That releases the shackle. Then you turn the lock around 180 degrees and turn the key back to the starting position and about a quarter turn anti clockwise. At this point the lock should come free of the shackle completely. To relock it simply do the steps in reverse.If you want the lock to function like a regular padlock simply remove the guard from the shackle and use as you normally would.Pros:A hard steel guard covers most of the shackle making cutting the lock off much more difficult.The complex unlocking sequence, while only somewhat cumbersome with the key, is a nightmare for picking (I've tried it).Cons:The lock has a learning curve but honestly not more than a few minutes of practice. Once you get it it's a piece of cake 🎂.The lock is probably a higher carbon steel. while this is good for cutting resistance it does make it more prone to rusting and if used outdoors will need periodic cleaning and maintenance. (I flush the lock with carburetor cleaner and swap with a cotton swab, then give it a generous lubrication with WD-40 or some equivalent)

Excellent qualityThis lock has stood up to over a year's woth of bad people trying to remove it to steal a bicycle. It has outlasted the would-be criminals. Good lock.

The media could not be loaded. I needed a lock to secure my bike. I bought this particular lock primarily because of a review of it by a superb lock picker on You Tube called "The LockPickingLawyer," who is clearly an informed lock guy and talented picker. He described this lock as "...the most impressive security wise laminated padlock that I've seen in a while." He also said, "...from the usability standpoint it's a bit of a pain in the butt." And I think he's right on both counts. It does strike me as a rather smart design (security wise), it's well built, and it looks pretty cool. But it can be a tad cumbersome to deal with, the lock comes apart in 3 pieces when locking/unlocking (shackle/guard/lock body). But for someone like me who lives a slow lifestyle taking a few extra seconds to "assemble" the lock is no big deal. But if I were a guy in a hurry I might find it a bit annoying to have to deal with the few added steps--and pieces-- it takes for locking and unlocking. At first I thought, no way am I going through this every time. But after about five practices I found to be not much more effort than your typical padlock. The pay off in this arrangement is that the key has to be turned twice for unlocking (and locking), and so any picker has the added pain of having to get past this double locking action to remove the shackle and guard. And considering how easy most padlocks can be picked by a good picker this feature seemed rather important to me. Even a novice picker might get lucky and "rake" it open, but then they'd have to get lucky twice. To me this is almost like having 2 locks in one. I like the shackle guard for the protection it gives against cutting or brute forcing the shackle. I also like that the lock has rubber padding around the bottom to prevent scratching your goods.I think this was a good buy. It seemed the optimal choice for locking my $275.00 bike, and I reviewed dozens of padlocks in the 25-$50 price range. No bike is ever 100% secure from theft, but at least I can feel confident I made the best security effort all things considered. And that's really all we can do, right? Rating a product is a very subjective thing. I give it four stars, only because 3 seems too few and 5 seems too many. I'm attaching a short vid of me using it. Please excuse the black and white tape. The small white tape is so I can quickly identify which side the longer shackle end goes in.

Sent me a used defective lock with rust, gouged up and the keys would not release. I purchased a new lock not a used lock! Extremely disappointing, I now have to return the lock! However, the lock is high security and high quality, if it has not been previously used, I would have kept the lock.Will not work on a hasp that is 1/2" wide horizontally.
