I love this lock because I don't need a key. My family all have smart phones with the app and electronic keys. When grandma picks up my kids from school I no longer worry if they have a key with them. My car is keyless too so I don't cary keys!
When guest come over it is a focal point upon entry, magic, no key, just touch the lock, Blue LED, and Bam it's open.
Installation was a piece of cake. Download the kevo app and it has a virtual step by step process. I never followed installation instructions like this. It was great, minimal reading, many pictures that help. These guys impressed me with the app instructions.
I always have my hands full with my lunch bag, gym bag, kids backpack, groceries, but I only need a finger to touch the lock. I love it, and others envy it.
