This is the second "smart lock" I have owned and it was a lot cheaper than the first one, but it is WAY better!! Everything works as it should and it was easier and cleaner to install than the previous one. And it has already lasted longer than the last one (Turbolock brand). I do have the minor issue that I see others having about the fingerprint reader not working in rain, but it's a really simple fix, just dry it and your finger with your shirt real quick and it works fine, lol! It is so easy to program and you can make it read just about any keyfob you might already have. I programmed my gym fob to it and it works great. The only thing about this I don't love is the batteries only seem to last about 6 months, but it is still well worth the 5 stars with that.I installed this finger print door lock in the garage door that enters the house, because I always walk in to the garage and lock my self in (the door swings shut on its own). So after being locked in my garage probably 20-30 times in the last 7 years I decided to install this devices. It works great. I found easy to install even though I had to drill an extra hole in my door. The devices user interface could be better but it gets the job done, I don't worry about locking myself in the garage any more. And the kids lover using their finger print to open the door. As far as safety it looks and feels very durable. You also get a key just in case, it runs on battery. We haven't had any battery issues.I love it, easy to install and looks great!!This is an amazing lock. Eady to install.This lock was easily installed, and works with Alexa (gateway sold separately). Overall I very happy with its functionality and appearance. The only problem I’ve had with it is that my dog easily opens the front door because of the handle design. Wish this came with an option a round knob instead of the lever handleWorks greatThis is a really bad product. Completely locked out and won’t let us to reset. Horrible item. Do not buy!This lock is easy to install, easy to set up on your phone and looks greatLittle confusion around whether it is locked now or unlocked unless voice says so.. voice is good.
