Love my new Halo Touchscreen Wi-Fi Enabled Smart Lock! My phone is compatible (won't work with older phone models), so that is great! It is easy to install and set up. My son usually forgets his house keys so this has been perfect for him! The app is great for allowing access during specified times too. The lock, itself, is big and beautiful. Gives a regal look to my door. Absolutely love the rekey feature. Love that you can check all the times it has been locked and unlocked. This product represents peace of mind in a lock!!!
