Can i just say im obsessed with this smart lock?! Im first of all in love with how easily and timelessly it took to install this door lock. The look and feel of this lock are right on point and the key seams to fit in the hole perfectly without getting suck while trying to take the key out after locking it. The app was a bit tricky to get this device product registered but with the help of the nice lady at customer service we got it figured out in no time! She also took the time to teach me and my husband how the product works, how the application works, and a few toubleshoot problems if we ever ran across them in the future. This product i would highly recommend and their customer service representatives are 100% outstanding!
