We love these. We have them on our rental property. What an engineering dream! We are able yo assign codes for property manager, cleaning crew, security, etc. and temporary codes for guests. 
They are user friendly, reliable and easy to set up. 
Another nice feature and the auto lock timer options. 
We want to get one of these for our primary residence as well.
As an interior designer, thank you Schlage  for not only offering reliable locks but also a large array of design option.
