The lock is made from metal, so it seems durable and should last for a long time. It’s not complicated to install, and programming the code is simple. However, there are a couple of downsides: First, you can't combine two keys together. Second, the code isn’t ordered. For example, if you set your code to 1234, you can also unlock it with 4321. This means that if you set a 4-digit code, your lock will recognize 24 possible combinations, which slightly reduces security. That said, it's not a huge issue since the lock has 14 buttons, which allows for 16,383 possible combinations, making it quite secure overall.
