I purchased this smart lock back in 2018 and have used it daily since. Easy installation, great design, wonderful concept however the product was overpriced and terrible. It would randomly unlock and lock throughout the day (even with me troubleshooting), HATED that I needed to buy an additional product to be able to unlock/lock when I was away from home (which was the main selling point for me), and most of the time the product wouldn't even work. Would not recommend, definitely save your money.
