I assessed several types of combination locks to use for a locker, so that I wouldn't have to carry a key around with me when exercising. I even bought and tested a few, and this one is the absolute winner at a very good price. It is slightly larger than the others, but that is because of its clever internal design for locking and changing the code.
I haven't subjected it to jimmying, so it's hard to say how well the metal frame would resist, and the dials have plastic wheels – I don't know if there are metal cylinders inside or if it's plastic all the way to the mechanism, which might make it easy to pry out with a screwdriver. I might buy another one to experiment on ;)
Robust construction
The length of the shackle insertion into the body is about 10mm! which is absolutely sufficient and beats most locks in this category.
It has an innovative click-in mechanism that you can't feel by hand! It doesn't use a projection on the rod, but rather a kind of tumbler inside the lock.
There is no gap between the wheels; you cannot reach in there with a metal shim
Precise and smooth movement of the wheels. The wheels protrude from both the front and back of the lock, making them easy to turn.
Perfectly visible large white digits on a black background!
The code is changed using a switch on the bottom of the lock, so you cannot accidentally change the code like on other common types of locks.
Great price/quality ratio
Just a heads-up: because it has dials on both the front and back, you have to be careful which side you enter the code on! The lock is completely symmetrical on both sides, but on one side there are two tiny white lines drawn near the dials – one above the dials and one below them. You need to enter the code on this side. If you enter it on the other side, the lock obviously won't open and you'll end up getting the wire cutters for no reason : ) And then you'll come and write a review here saying it got jammed; )

I bought it now and so far I have a good feeling about it. I reckon it would be a good idea to squirt some silicone oil into it occasionally. The setting code is in the package, you need to open the paper on which the lock is placed.
it's a little guy, I was expecting a little guy, but it feels pretty solid in the hand. we'll see what they can stand outside on the gates
The code rotates so that it can be caught from both sides see photo.

after a few months of use, it is difficult to scroll through the numbers. Both locks do it. Otherwise, ok

After a few weeks out, he got stuck. Probably rusted, even though it is certain to be used outdoors. Alza is refunding the money, which is great, but I still have to figure out who will cut it off, I'm not equipped to do that.

It makes a good lock for situations where you can't expect forced entry with some long crowbar, steel mallet and chisel, or accu-flex. That is, wherever it is not advisable to have a key to the lock somewhere, but at the same time it is not a deserted remote area, i.e. the use of brute force tools to overcome the lock is not expected. I recommend the lock for the price - it is wonderful to see the numbers.
the numbers are white - beautifully visible
the lock is as if plasticized, but otherwise it is fortel
the code change solution is implemented with a sliding button and no unwanted code change is likely, well designed
for the price it's a solid product
I guess for that price I can't expect automatic sorting of numbers to 0000 after locking the lock into the petticoat, it means the necessity to always "scatter" the numbers after locking, this function is available in few locks
