Great item and I wish we had gone this route ages ago. Simply not having to keep track of keys for the family, plus hiding spares outside, and getting replacements cut, means that this will substantially pay for itself in due course. The build, weight and finish are also just right for the external appearance of our front door, which is of an older style with other brass elements - I was initially sceptical about adding something potentially cheap and plastic in such a prominent position but that is certainly not the case with this lock and it looks great. Not yet integrated the module into other smart features but this was secondary for us anyway - this is doing exactly what we needed it to and we would recommend it.
