Home security remains a top concern and priority for many, especially those who share living spaces with others or travel often. For this reason, supplemental locks and security gadgets exist to give users peace of mind. However, many of those options can put a sizable dent in shoppers' pockets.

Amazon shoppers and TikTok users have since found an affordable solution in the top-rated device aptly titled Addalock, with some even deeming it a "life savior."

Addalock, described as "the original portable door lock," adds an extra layer of safety, security and privacy to your space.

The pocket-sized item works at home (or during travel) and is particularly ideal for apartment living, hotel stays, student housing, school safety procedures and lockdowns. The product's description added that it is also "great if you are staying at an Airbnb or any other short-term rental."

While some other lock devices can be a hassle to configure and set up, Addalock installs in seconds.

As outlined in a simple guide shared by the brand, it only takes a few short steps to get Addalock up and running.

First, insert the back of the handle into your door's lock latch to test for fit. Then, open the door widely enough to insert the claws into the Addalock strike plate. Once the claws are securely in place, close the door, and the device will stay put. And that's it! The Addalock is now installed. Simply tuck the red tag on the side of the latch so it doesn't hang, and go about your day.
