It's very simple to use, and it has some great functions which are very useful to our small business (it was just started one year ago). Their customer service is also excellent, they have always respond quickly and help us with any of our questions in time. I personally dislike that we can't integrate it with our website, so we have to upload files manually every time we want to make changes or add new features. Integrating with our website would be perfect for this lock, as we don't need to connect it with our laptop all the time. It gives us greater security and peace of mind knowing that our house is locked safely when we're away from it.
