First off if you don’t have a smartphone with email and texting then this is not the lock for you as you have to download their app, it’s mandatory. Second the massive legal contract you have to read and sign just to unlock your own front door baffles me. Other than that the instructions were awesome, straight to the point with lots of references to what to do if certain issues arise so you don’t have to start reading the instructions over. It was very easy to set up, it comes with a key just in case you forget your phone or the batteries that operate the lock die. I would give it 5 stars as it’s an awesome lock with cool features and very modern look to it, topped of by probably the easiest fool proof instructions I’ve ever read.
