Ive had my Kevo for roughly one year now. There was only one incident where the lock wouldnt unlock for a 10 minute period of time where I thought I was going to have to call a lock smith. Given Ive accessed my house over 365 times with only 1 scare, the hardware is good to say the least.
My complaint comes with the app. When I was using the lock every day when I first got it, I could simply have the app running in the background of my phone, phone in my pocket & unlock/lock my deadbolt. To be honest I went a period of time without replacing the batteries and just recently did because I thought the convenience would be nice to have again, only to find since then there must have been some updates because now the lock will only work with my phone open and the app opened. This COMPLETELY ruins the convenience factor of paying 2-3x the typical deadbolt. I purchased this so I didnt have to take anything out of my pocket. This actually makes it more inconvenient than a regular deadbolt.
Instead of the old fashioned way; hand in pocket, grab key, stick key in and turn. I now have to grab phone out of my pocket, unlock my phone, double click to find the app running, select the app then touch the deadbolt.
So I thought to myself, there must be a setting to allow the convenience of keeping my phone in my pocket and accessing my lock like I used to when I first purchased this two years ago. Go to the setting icon next to my name, try to select Preferences & boom: app crashes. Yes Ive tried deleting, re-downloading & entering my credentials with no luck.
Needless to say this app has completely ruined a good piece of hardware. I will be buying the more advanced competitor that has a keypad built in and allows me to unlock/lock remotely for guests.
If I was only reviewing an app this would receive 1 star, however I gave it 3 because of the hardware.
