I have purchased two, one for my sister and one for my self. I took a little longer time before I write this review, because I can discover more issues. So far the August smart lock gave me no issues and it's a great product. Before I install anything, I always go on YouTube to search and watch DIY of installation on any of products. I have installed August Smart Lock Pro+ for about a month now and the only issue I have is one error message. To warn me the lock has an locking issues, I make the deadbolt lock plate adjustment on the door frame and it works perfectly now. I took a little time to install the magnetic sensor inside the deadbolt lock insert plate by the door frame. I want to make a better look instead drill two screws holes and a sensor sticking outside the door frame. Please see the two pictures I attached. The only downside is if you decide to use the auto function to lock your door, please make sure you either have a key or your phone with you. Otherwise you will be lock outside of your home while door is closed. I found out if you want to open the door for someone else while away from your home, you will have to refresh the app before you can do so. That I don't like, otherwise it's a great product.
