  • Full review, owned since initial product launch!

    I’ve had this lock coupled with the connect for at least three years now literally since the initial launch. At the time this was a one of a kind product and to this day I couldn’t be happier with my decision to buy it. Initially it was definitely a little glitchy, but that is to be expected especially with new bleeding edge technology. The bottom line was I simply couldn’t wait to get one and it immediately changed our lives for the better. Happy to say that August quickly resolved all the bugs within a matter of months and I have had no problems ever since. I’ve specifically read every one of the negative reviews and the vast majority appear to be operator trouble. This lock is not overly technical, but it will definitely present challenges if you don’t understand and aren’t comfortable with smart technology. My 70+ year old mother is a prime example of someone who should definitely steer clear of this type of technology. Not just seniors, but anyone lacking a good understanding or interest of smart technology will end up writing one of those bad reviews. Other relevant solutions like a simple keypad lock are definitely a much more sustainable alternative for anyone lacking interest or technically challenged like my mom. I have a strong Internet connection and I followed the specific instructions for not only the lock, but also for the connect. I can be anywhere in the world and unlock my front door within a matter of seconds, every time of course as long as I have a signal on my phone. I personally travel a lot and let in people all the time. It’s so comforting for us not to be handing out and losing track of our house keys and garage door openers. Moreover, to be able to look at my phone app while I am at the airport and quickly see that I didn’t forget to lock the front door is pretty cool. That said, my one and only complaint is that there isn’t a battery level indicator. You only get notified through the application when the batteries are low, but not before that and that’s absolutely cutting it too close for me. The only solution I could muster was to create a reoccurring reminder every four months in my calendar. It’s definitely not ideal, but thus far it’s worked for me. Hopefully August developers will soon figure out a way to add a battery level indicator to the app in a future update. I know this was a rather lengthy review, but I really tried to cover everything I could think of. So, hopefully I addressed most of the questions to those that are unsure whether to purchase this lock or not. I know I’m thrilled I got one!
