I absolutely love this lock! Installation is not too difficult when following the directions. You can connect it to an app that will allow you to give individual codes for each person and it even tells me when and who unlocked the door! I can scheduled when the lock is enabled! The only issue I have is sometimes the buttons will not beep when pressing. It will normally glow green when the buttons are being pressed. Overall, this is no convenient rather than fumbling for keys and I highly recommend!
