I've just completed assembling and testing the lock and it works amazingly. The different options of unlocking are so convenient. Keys, app, card, and touch based. The packaging is high quality like an iphone and the hardware itself has a high level of craftsmanship. This is not a cheap lock and I trust this will work very well for my front door. I was able to easily assemble it with quite simple instruction. My initial concern with this was the battery power operation and assembly but the way the batter installs through the end of the dead bolt makes sense. Yet still has a strong deadbolt. Highly recommend this lock if you need to share accessibility for multiple people or you lose keys all the time like me. I plan on using this lock for all of my houses including rental properties.
