Portable/Travel Door Lock
No Entry - Even with a Key!
This portable door lock stops silent unwanted entry even by someone with a key. It cannot be "picked" so will stay in place even when the door knob is turned, or if the lock is picked or broken.
Portable Hotel Door Lock
While the Portable Door Lock’s primary design is to prevent strangers to unwanted maids from entering your hotel room, it is also essential if a traveller is planning to or may end up staying in budget lodgings. For that matter, the Portable Door Lock is good to use in any situation where you want the additional protection from someone entering your room with a master key.
Now You Can Lock Your Door –Even if it Does not Have a Lock!
With the Portable Door Lock you don't have to worry about privacy and security when it comes to doors without locks because this device turns non-locking doors into locked doors simply and quickly.
I've used this lock a couple of times and found it gave me the peace of mind I needed to have a good nights sleep. No one attempted to enter so I can’t say anything about the strength of the product, but anything that causes a would be trespasser to take more time or make a disturbance and wake you is a good thing. If you suspect a place has dodgy staff, having something they aren't expecting is a good measure.
UPDATE: Unfortunately these are no longer available.
