This product was exactly as described. It was extremely easy to install and the instructions were not needed, despite being detailed. The locking screw was too long for my door, but being a standard size allowed me to use the locking screw that the previous lock used, so there was no issue there.
The lock came with a card and reference so as to be able to purchase a new key online if necessary. After a few months of use the lock is still working well and I've had no issues whatsoever. It provides a high level of security with the ease and simplicity of easy exit. A great product.
