Master Lock 1500iD Locker Lock Set Your Own Directional Combination Padlock, 1 Pack, Blue

These locks are great in theory, or if you don’t want to change the combination.The basic problem is that when you set a new combination, you can’t be certain it has been correctly registered until you close the lock. At that point your new combination either works, or it doesn’t - and if it doesn’t you’re stuck with a useless lock that’s good only for the bin.The mechanism is a bit temperamental. About 1 in 10 times that you try to open it with the supplied 4-move code, it doesn’t work. If you enter a new, longer code, the chances of something not quite registering are really quite high. I’ve ordered two locks. For each, I set a new 11-move code for each. In both cases, the lock then wouldn’t open and had to be thrown away. £60 wasted. I appreciate this is because the new code wasn’t correctly set, but I am not daft; I followed the instructions to the letter, practised with the locks a lot beforehand, and set the code extremely carefully. They just aren’t reliable. I suspect this is the main reason they are discontinued. If you do get lucky and manage to set a new code, or are happy to stick with the existing (less secure) 4-move code supplied, then this is probably a great product.
