I recently upgraded to the LEELEN Smart Lock Front Door Set, and it's been a total game-changer. The fingerprint sensor is lightning-fast—seriously, it unlocks in under a second, even with groceries in my hands. No more fumbling for keys!

The app control is my favorite feature. I can lock/unlock remotely, check who’s coming and going (hello, peace of mind), and even share temporary codes for guests. Last week, I let my dog walker in while I was at work—no awkward key exchanges needed.

Installation took me about 20 minutes (yes, I timed it). The included video made it foolproof, though I did have to drill new holes since my old lock didn’t align perfectly. Pro tip: Use the provided screws—they’re designed for this lock.

Build quality feels premium—solid metal, sleek black finish that doesn’t show fingerprints (ironic, given the main feature). It survived a heavy rainstorm last week thanks to the IP65 rating, and the battery life has lasted over 3 months so far.

Minor gripe? The Bluetooth pairing was finicky initially, but once connected, it’s been smooth sailing. For the price, this outperforms big-name brands I’ve tried. If you want a secure, tech-savvy door upgrade that doesn’t scream 'overengineered,' this is it.
