I have had the Kevo 1st generation Bluetooth lock for 6 months now, and occasional glitch aside, I have been very happy. My phone remains in my pocket and when I touch the lock it will lock or unlock depending on the current status. Moreover, I can assign virtual keys with set schedules for others in household, guests, and service professionals.  With the wireless router accessory , I am also able to lock and unlock the door for guest when I am away. 

Unfortunately it is not perfect, and sometimes the bezel does not react to touch, or it spins endlessly. When that happens I just need to close and restart the app. 

I highly recommend this lock as it also gives you a physical key alternative.
