Review on Enhanced Portable Door Lock with Multi Size Locking Options for Enhanced Home Security and Privacy – Ideal for Travel, Hotels, Airbnb, Home, Apartment, School (Red) by Pat Peoples

I tested three of these types of door locks. For me this one was the winner and cheapest as an added benefit (money wasn't my main concern). The Adalock branded version is a fraction of a millimeter thicker than this, but it also fitted my door more freely. ("Portable Door Lock") was more convenient and actually worked better (at least for the door I use) because you could completely detach the red piece from the bracket (which prevents the door from colliding when closing). It also has fittings for two sizes of doorways. This product (the product page you are looking at) was a clear winner for me on every level. There was even a cute bag in the kit.
