After reading this review, I am even happier with the three Schlage Encode Plus locks I installed this fall.
The Encode Plus is, by far, the best model I have encountered. Three ways to open: keypad, iPhone/Watch, or traditional key.
I previously had two different generations of the August lock. Their version of the keypad is cheap, flimsy, and unattractive. The latest generation went through a pair of CR-123 every three to four weeks.
A neighbor has the Yale lock, which has only a keypad facing the outside. That's great until the battery dies. There is an emergency way to access the lock with a dead battery that involves holding a good battery to a set of terminals on the bottom to the lock. It works, but it's cumbersome. I helped my neighbor access the lock a couple of time using this method.
Even the Schlage smart locks I installed in 2017 were better than both August and Yale, in my experience.
Schlage's Encode Plus is $320, about the same price as this Level device.
