I bought this lock immediately once I had the chance to purchase it as I was eager to employ the same keyless entry to my house as I had for my car. Unfortunately, the execution is wholly lackluster. When it works, it's perfect. However, it frequently takes more than one tap on the lock to open and that's IF it opens. I frequently find myself having to bring the app to the foreground on my iPhone 6 just to get the lock to work, even though I never close the app on my phone
