This is the Best smart lock on the market today. My family and I have been using Schlage Smart Locks for many years because it offers uncompromising security, durability and peace of mind. We are currently using the Schlage Encode Plus Door Lock built with Thread Technology so we get instant accurate notifications when the lock is open or closed and by which family member. I highly recommend this lock to everyone that is looking to purchase the best Smart Lock for their home!
