I used to work at a home improvement store in their hardware department and I used to have to change the displays to their locks several times throughout the year, so I've installed my fair share of different styles. This lock was so easy to install and is very simple to use! I love that my husband is able to go out running and not have to carry a key with him, all he has to do is put in his code. It's so simple and the buttons have a great coating so they aren't being rubbed off with use.
