Tick 50% off coupon. Bit of a warning: Reading reviews it seems you need a bit of a gap in the door for it to fit and a lot of reviews say it doesn't fit Australian doors. Still may be useful if you are traveling to some shady places overseas.
CamelCamelCamel.
going through the pictures. still cant figure out how this works
You get an audible warning that someone is entering your room when they accidently snap this thing, whilst attempting to open the door.
Hahahah
Essentially, the round/square hole is secured by the part of the door that keeps it closed (between the door and the doorframe)
The red thing has a metal knob on one side that you can put through the love heart/triangle shape that sticks out to the door-side slightly. This essentially blockades the door from going any further
The second picture offers the most clues. What stops it from falling down when someone tries to open the door? I don't know. I own some of the Qicklock ones and that's kind of their method
Explaining with words is hard but I've done my best
Thank you mate. Appreciate it!

I have one. It works well, but in some doors, I couldn't manually lock the bolt. Majority of the doors I've tried it on work though.
