Let me start by saying this lock has been a game-changer for my forgetful family. The keyless entry is fantastic when you're juggling groceries and don't want to fumble for keys. I particularly love being able to create temporary codes for house cleaners or dog walkers - no more hiding spare keys under doormats!

The installation was surprisingly straightforward (took me about 15 minutes), though I did struggle with the programming at first. Like many reviewers mentioned, the instructions aren't crystal clear about which side of the lock/unlock button to press during setup. Pro tip: always press the 'unlock' side when programming!

Where this lock really shines is its versatility. The auto-lock feature (adjustable from 10-99 seconds) gives me peace of mind knowing my door will always be secured. However, as one user pointed out, the maximum 99-second setting can still be too short if you're doing quick outdoor chores - I've been locked out while taking out trash more times than I'd like to admit.

After three years of daily use, I'm noticing some button sensitivity issues similar to other long-term users. The '3' and '6' buttons now require firm presses that weren't necessary initially. Battery changes didn't help, suggesting it's a wear-and-tear issue rather than power-related.

The warranty situation is concerning - Amazon's vague policy makes me hesitant to fully recommend this for long-term use despite its affordable price point. That said, for renters or those needing a budget-friendly smart lock solution, it's hard to beat the features you get at this price.

Final verdict? Great starter smart lock with impressive features for the price, but may not withstand heavy long-term use. If you're tech-savvy enough to work through programming quirks and don't mind potentially replacing it every few years, it's worth considering.
