I absolutely loved how easy this was to install and set up. It came with instructions on how to install it and wasn't hard at all. I was able to do it by myself without any help. Getting the app up and connected was the longest part but it's step by step so there's no confusion. The lock is able to be opened with a code or a key which is great for if someone forgets the code. The design of this is very stylish and beautifully made. I'll be getting one for my backdoor also.
