Overall good product, Safe.co.uk have good customer service and are very helpful.

The lock isn't quite as advertised (on here and on the manufacturers website, it says external use but this lock isn't weather proof and the manufacturer tell you that you have to make it water proof yourself (more time and money messing around trying to do so), they should be clear about this and mention it in the instructions. Ours got full of water and stopped working, but Codelocks have dispatched a new circuit board. So mixed feelings about this lock, it's not exactly cheap, so would expect a little better.
