These locks are awesome. They work with wifi and Bluetooth, are self calibrating, easy to install, have a long battery life, are biometric friendly (actually works very well), has a keyed backup, and is very high quality. The keypad touch screen is well lit and accurate to the touch. You can operate the lock remotely, using the app, and are alerted, through the app, every time the lock is used. I really can't think of any way to improve this product.
