(This review was collected as part of a promotion.) The Weiser Halo lock has all the bells and whistles. I like the convenience of a pin to unlock the door in case you forget your keys. The coolest part is the app, you can easily unlock/lock the door from anywhere- great to let anyone in without having to make multiple keys! I love the ease and sleek design of this lock. The instructions are so easy to follow, and the box is organized into each step of installation.
