I never realized how much peace of mind a tiny metal device could bring until I started using the Addalock. Whether I'm at home or staying in a sketchy Airbnb, this little gadget makes me feel like I've got a personal bouncer for my door.

The first time I used it was in a hotel with a dodgy-looking latch. Slid it into place, closed the door, and bam - instant fortress mode. What shocked me was how rock-solid it felt when someone accidentally tried to open my door thinking it was their room. The door didn't budge an inch.

As someone who constantly misplaces things, I love that it lives permanently in my travel toiletry bag (in its cute red pouch). At home, I use it when working remotely - no more surprise landlord visits interrupting my Zoom calls. The maintenance guy actually complimented it when he finally got proper notice to visit!

The genius is in its simplicity. No tools, no installation headaches - just slide and lock. Though fair warning: watch the YouTube demo first if you're spatially challenged like me. Once you get the hang of positioning that metal plate just right against the strike, you'll be addicted to that satisfying 'click' of security.

After six months of use everywhere from college dorms to European hostels, my Addalock still looks brand new despite being tossed around in luggage. That engraved logo isn't just for show - this thing is built like a tank. Best $20 I've spent on peace of mind.
