Works great when locking/unlocking using our iPhone, whether we're in the house or somewhere remote. The auto-unlock feature is also really nice. When we pull in to the garage, it automatically unlocks for us. The only negative is that it rarely works using our Apple Watch (maybe 20% of the time). I've contacted their customer support and there is nothing they can do to improve that. This would be a great feature if they could get that to work though and make it a 5-star product. And I will say their customer support is quick to respond, so that adds value to this product.
