I've had this product since January and had limited success with it. Generally what I have found it that it just doesn't connect with my cell phone when trying to open the lock by touch. I usually have to dig out my phone and re launch the kevo app for it to work. I have re calibrated following the video several times with the same results. If the phone is in my pocket with the app recently launched it will work about 30% of the time. My wife has the same experience. I finally just put the bluetooth key on my ring, which I find quite bulky, and it works about 75% of the time. Still, I'm disappointed that it doesn't work as promised on the website. It is nice to be able to make sure the door is locked from bed though. [This review was collected as part of a promotion.]
