I bought two of these for our new home and we have been using them for about nine months. I had issues with one of my locks from the start. The lock kept jamming. Customer service was very helpful they sent me instructions and it was resolved. I have had to reset the same lock twice because it keeps having the same issue. I have my phone set as my key but my boyfriend prefers to use a regular key and often when we are leaving together and he is using his key and my phone is in proximity it counters his actions. My phone will sometimes work perfectly but often it requires me to log into the app before it will which is no more convenient than fishing for your keys. So yes it's a good product but it has it's frustrating moments.
