This is a great product in concept, but execution is extremely poor. I've had mine well over a year and am beyond the point of trying to get the bluetooth to function properly. I use it as any other lock. Except on the occasions when i walk out of the house when my phone is still inside and the door locks behind me. Of course when I'm outside touching the lock, it doesn't work or sometimes it does - you just never know. I'm normally pretty presistent, but after numerous attempts, just gave up - poor working technology wins. Been through the software upgrades and they didn't improve performance.
