After finally installing the Wappa Baby Door Lever Lock, I immediately appreciated how straightforward it was to set up—no fuss, no tools needed. I was curious about how well it would hold up on my flat panel door, especially since I’ve struggled with locks that don’t stick or fall off easily.

The size of the lock is compact but sturdy, measuring 3.25 inches long, 1.5 inches wide, and 4.5 inches high, making it easy to handle.
