I recently upgraded my front door with the LEELEN Smart Lock Set, and it's been a total game-changer. The fingerprint sensor is lightning-fast – I can unlock my door in under a second, even with groceries in both hands. No more fumbling for keys!

The auto-lock feature gives me peace of mind when I'm rushing out the door. It automatically secures my home after 30 seconds, which is perfect because I used to constantly double back to check if I'd locked up.

What really surprised me was how well it handles different users. I've programmed fingerprints for my family members and created temporary codes for dog walkers and house cleaners through the TT app. The activity log lets me see exactly who's coming and going – super helpful when my teenager claims they 'definitely came straight home after school.'

Installation took me about 20 minutes (I'm not particularly handy). The included video guide walked me through every step, though I did have to drill new holes since my old lock had different screw placements. Pro tip: Use the included hardware – mixing parts from your old lock doesn't work well.

After three months of use through rain and extreme temperatures, the lock still looks and works like new. The IP65 rating means I don't worry about weather damage, though I did notice the touchscreen can get sluggish in very cold weather until it warms up.

The only minor hiccup was initial Bluetooth pairing – it took a couple tries to connect properly. But once set up, remote access via WiFi has been flawless. Being able to let in a neighbor to water plants while I'm on vacation (and watching them do it via my doorbell cam) feels like living in the future.
