## Description

Durable stainless steel padlocks with a reinforced body and shrouded shackle offer maximum weather resistance and protection against bolt cutter attacks.

Review: Sturdy lock that does exactly what a lock should..... - I’ve been using this on my storage unit, and it’s exactly the lock I needed. The locking action is smooth and positive, so once it rotates shut you feel confident it’s doing its job....if anything, it feels too loose when moving, albeit solid once locked. A cylindrical lock like this was also a requirement of the storage unit company.... It feels solid and the stainless steel discus style gives a reassuringly robust impression. It’s clearly meant to withstand weather and everyday use rather than be a delicate bit of hardware. That simplicity is exactly what I wanted for my storage unit, albeit it is an internal unit, so not open to the elements..... The only slight gripe was getting it out of the packaging, which took a bit of doing, but once it’s in place it’s been reliable with no fuss. If you want a no‑nonsense padlock that works hard and doesn’t let you down, this is a good pick....excuse the pun! It also comes with 4 keys which is really handy for someone like me!
Review: Ideal shed/container locks. - So I have a rectangular box in the garden I store my wet tools in, and a shed with bolt. These locks work perfectly fine, I wasn't sure on the rounded option as I prefer a standard padlock which I can lock without the key where as the circular locks you need to key to rotate the clasp. However with the shed especially I often locked it then found my keys were left inside, so that's resolved this problem for sure. Locks themselves feel sturdy, enough with a plastic cover that can go across the key insert (which you'll never use but it doesn't get in the way!) And quality wise feel perfectly fine sure they aren't going to fend off someone that's determined but they are better than a unknown generic/cheap padlock and should withstand the weather well while stopping any random chancers getting in.

### ⭐⭐⭐⭐⭐ Sturdy lock that does exactly what a lock should.....

### ⭐⭐⭐⭐⭐ Ideal shed/container locks.
*by M***. on 9 February 2024*

### ⭐⭐⭐⭐ Only received today however….
*by D***E on 22 January 2023*

I have only received this item today but seems good quality for the price. Heavier than I thought it would be, have now put on gate so will soon test the weatherproofness. Keys seem thin for the weight of the lock but if they work that’s ok. You do get 4 keys. I like the way the lock retracts into the casing and isn’t a separate piece like my last really expensive lock which cost three times this one and lasted two years. Took a lot of effort getting the lock of the OTT packaging though, which was really not required. I’m also not sure what a limited lifetime warranty means! Even though I went on their website to check, so disregard the lifetime warranty as the clauses seemed a bit confusing. Over all I’m happy as it was the cheapest lock but wasn’t the most expensive.
