    • Heavy Duty Locks
Style: Combination
Review Image by Psquare Psquare
Review Image by Psquare Psquare
I needed some good locks to lock down my father’s gates to his fence as we go through probate to settle things. These locks are great to protect from gaining access to the gates. I had some of the thinner metal locks on the gate and some cut through that lock. Well, they will not cut through these locks. The are really heavy and great quality. I did find the instructions a little hard as mines got torn off when I opened the packaging and it took me an hour to try and understand where are they located and I finally found the passcode and stuff. It was torn off with the packaging so I never found it where it said it’s was. Need to do a better job of placing the passcodes where they will not get torn with the packaging and then you can not find it as I thought it did not come with a passcode. Other than that, excellent heavy locks to secure a gate or anything more securely. They are expensive but worth the extra cost. ... show more

this lock and it's packaging and instructions have enough egregious problems that indicate a total lack of respect for the consumer that I am giving it a1 star review, I don't care how good it is once I'm able to use the POS, it'sstill a POS but #0 IT DOESN'T OPEN WITH THE COMB O PRINTED IN THE PACKAGE!#1 advertising print on the back too small to read #2 no instructions to change the combo on the package (I think) #3 the instructions I downloaded ARE STILL TOO SMALL TO READ and won't zoom enough to read and I can't even download a simple text magnifier from sorry google play for android! #3 I dialed in the combo under the key and the lock still won't open! #4 there is a rubber case around the center and the dial face that makes it harder to spin the last dial that I cut off..#% I go to the stupid master lock website and can find NO instructions for this lock no literature or support whatsoever! ... show more

Unfortunately it's a little hard to scroll numbers sometimes but still the best lock for security and ease of use

    • A Master Lock that is actually half decent!
Style: Combination
Review Image by Sawyer Sawyer
Review Image by Sawyer Sawyer
As someone that picks and decodes master locks frequently and publicly laughs at them for how bad they are, this is ACTUALLY a half decent lock. Pros: 1. Thick lock with boron carbide shackle that is very difficult to cut. I tried cutting it with a pair of Texas keys and to no avail. (See photo) 2. Due to the grittyness of this lock's internals decoding it is near impossible to achieve. However this can be a con (see cons below). Cons: 1. The lock's internals are gritty and comes with no lubricant in it at all which makes it a bit hard to open and close as well as using the dials. What this means is that in the winter time it could potentially freeze up and become unusable. However, all you need to fix that is to shoot it with WD-40 then apply lock lubricant in it afterwards when you receive it. Do this every few months and it should work perfectly. 2. The lever that pulls the shackle down is a bit flimsy and has potential to break. Make sure it's in good by knocking it in with a hammer otherwise it might come out. So because of those two con reasons I will give this a 3/5. ... show more

    • Excellent quality
Style: Combination
I was hoping the metal casing would be a bit thicker. But for around $20 they seem like good quality. No issues yet with number dials getting stuck.

    • Very Good Lock
Style: Combination
Needed a lock for a Pod shipment - This one is easy to reset the combo with the included key, easy to open and easy to lock. Quite heavy and feels like a secure piece of hardware. Much easier to use than those locks with the combo in the bottom I hope I don't need to replace it - but if I had to, I'd get one of these again. ... show more
