Does the job well
A very good and strong padlock

Easy to set the new combination, very secure design.
These are the best value padlocks I have found. They're so solid, I bought them for the garden sheds to replace the key ones since multiple people in the house use them. Being able to set the combination is a handy feature, I could set them to something all the users can remember. I think you would need a grinder or something to hack off that lock because the design is too secure for an opportunist. It's only been in use for a few months now and there is no sign of rust or weathering, I'll update the review if that changes, but so far it's weatherproof.

Packaging !
Never seen package like this before - 15 minutes entry time ! You need to unlock it, before you can take it off the packaging ? (Stops thieving from shop displays maybe) After discarding the loose rubber facing, and filing off some sharp edges, we have a very good lock. Love the way the turning dials are easily accessed from front and back, and the large gate for cables. Robust enough to withstand a "two spanner" attack, but unsure if the reset key may provide a way in. The outside SS cover was very smooth, but inside corners are sharp and hinder the clasp opening. Feels like good solid protection for items inside my garage.

Disappointing product.
Received the padlock fine, located the code on thee rear of there package, very tricky to pull off the package to fine this...A very strange place to put such a code, especially as the expectation is to reset this padlock. as soon as you use it. Tried the code provided, the padlock did not work, in addition the numbers do not line up as a normal combination padlock should. Attempted many times, in the various 'states of numbers', with no success, so the padlock remains locked! Another product that sadly disappoints.

Too fiddly and hard to open
Not as impressed as I hoped I would be, it is very secure and sturdy, however you have to be extremely accurate when putting the numbers in, they must be bang on in the middle of the dial, it's also quite difficult to see the numbers unless it is very bright, they are quite small and not very brightly marked, and it is very easy to make the mistake of looking at the back of the padlock rather than the front. We bought this for a shared entry system, and some of the residents complained that they had to go and get their reading glasses to open it, and others couldn't work it at all.

Easy to use and sturdy
This lock is super easy to use. The combination wheels are smooth and gives a nice click when positioned correctly. It feels well made and solid. I like the thumb lever to open and close the lock. Easily done with one hand. I’m using this lock indoors but it looks like it would hold up to the elements outside really well.

Very solid, looks great quality!
Seems very solid, it’s easy to use, very straightforward instructions, size is good, look good, I do believe that would be weatherproof, the time would show, it’s locking the garage door at the moment, does the job!

Das Schloss sehr massiv und schwer. Das empfinde ich als gut und angenehm. Es hat jedoch einige Zeit gedauert bis ich verstanden habe wo der Zahlencode zu finden ist. Zusammen mit der stabilen Kette, die ich gekauft habe ein sehr sicherer Schutz.

Very solid, heavy duty lock. Comes with a key (don't loose it!) to reset the combo when you need to. Number dials are tough to turn, but I take that as a sign of it's robustnesss--if you have weak fingers, maybe not the lock you want.

Başarılı kilit, köy evinin bahçe kapısı için aldık. Sizi gerçekten korur. Ama amazonda 560 tl den girdi fiyatı iade ettim en son 360 tl ye aldım. Neredeyse yarı fiyata. Buna dikkat etmek lazım.
