Let me start by saying this lock is a BEAST. The ULTRALOQ U-Bolt's 5-in-1 entry options (keypad, app, auto-unlock, shake-to-open, and physical key) make forgetting your keys a thing of the past. Installation? A breeze - I had it up in 15 minutes with just a screwdriver.

The auto-lock feature has saved me countless times when rushing out the door with armfuls of groceries. And that backlit keypad? Lifesaver for midnight snack runs. The build quality shocked me - that solid brass cylinder feels like it could survive a zombie apocalypse.

BUT (there's always a but)... The app needs work. Where are my scheduled locking features? I shouldn't need IFTTT just to auto-lock at bedtime. And that firmware update process? More frustrating than assembling IKEA furniture blindfolded.

Pro tip: Wait for the green light after entering your code - that 1-2 second delay had me thinking it was broken at first. Also, invest in the WiFi bridge if you want remote access - though placement can be finicky.

For vacation homes or rentals? Gold. Creating temporary codes for cleaners/guests is genius. Just wish the numbers were more visible in dark - watching guests fumble is awkward.

Bottom line: At this price point, it's 90% amazing with 10% 'please fix this'. Would buy again despite the quirks - just maybe wait for app updates first.
