Let me start by saying the Addalock is a game-changer. As someone who frequently travels and values privacy, this little device has given me peace of mind in hotels and Airbnbs. The metal construction feels sturdy, and installation literally takes seconds - just slide it into the door latch and you're protected.
What surprised me most was how versatile it is. I've used it at home when repairmen unexpectedly show up (why do they never call first?), in questionable motels during road trips, and even in my college-aged daughter's dorm. The fact that it works on most inward-swinging doors without tools makes it incredibly convenient.
The security aspect is impressive. I tested it by having my husband try to force the door open - no luck. The lock held firm even against shoulder checks. For travelers, especially solo female travelers, this provides an extra layer of protection that most hotel locks simply don't offer.
One minor drawback: It does require about a quarter's width gap between door and frame to work optimally. My front door was slightly too tight initially, but adjusting the strike plate solved this easily. Also worth noting - while extremely durable, the metal can scratch certain door finishes if you're not careful during installation.
The included red pouch is a nice touch for travel organization. I keep one in my suitcase and another in my work bag for unexpected overnight stays. At under $20 per lock (the 2-pack is even better value), this is some of the best money I've spent on personal security.
Final verdict? Whether you're a frequent traveler, live in an apartment with questionable locks, or just want extra home security without permanent modifications, the Addalock delivers exactly what it promises - simple, portable protection that actually works.
