Door Lock, PENMAMA Portable Door Lock for Travel,Security Devices, Additional Aafety and Privacy Door Locker for Home, Hotel, School, Apartment, Dormitories

This is awesome small compact security lock. If you stay at air bnb's alot, this lock is a must. I gave this to my daughter so she can lock up when she stays overnight anywhere. Sleep a little better knowing no one will be disturbing you.

Fits in your pocket. No tools needed. Works on open swinging doors. Set up or remove in about 5 seconds. Is effectively a quick easy way to lock any average door in your house. Perfect at keeping out your landlord, housekeeping at hotels, or anyone else that you want to keep out. Keys are ineffective at opening a door that is locked with one of these. The best part is that absolutely no modifications need to be made to the door or frame or anything else. It uses no key so your landlord cannot request one or make you pay for modifying the lock. Its cheap, effective, easy to initiate, no installation needed, light weight, portable, durable enough. Its a no brainer! Buy it if you are considering it.

it is not fit in door's hotels

It wasn't expensive so I thought I'd give it a try because we had a trip coming up. Two different hotels in two different towns and this lock didn't work on either door. The shaft is way too short to work. Don't bother.

As a single girl who travels, and even as a person who travels, I always sleep better when this lock is on my hotel door. Not only does it give me peace of mind, but it completely prevents someone from entering your room. There are some people who say this is a fire risk… which it may be however I find the odds of someone breaking into your room more likely. Either way, it’s easy to use (much easier than the other door locks on the internet) and simple to use. All my friends have them and love them! They are like a stocking stuffer!

My door type wasn’t specified and I should’ve read measurements and measured my door (my fault there) but it is super sturdy! Probably works well for other door types. There’s barely a gap between my door and the frame so that’s why it doesn’t work well for me.

Product was manufactured with light weight materials and design was sloppy with regards to threads

Been staying out of town every week for work so got this. Absolutely worth every penny and one purchase I am glad I made. Easy to use. The door does not budge once fully engaged and tightened. Not only did I try it, but I forgot to put out the do not disturb sign and housekeeping tried it. I feel secure in my room now. I used to always put my purse on the floor right next to me but now I leave it on the dresser. The only thing is the metal does leave a tiny dent in the door frame so if you're in a fancier place where that might be a problem you might want to put something under the metal piece. This is absolutely not leaving my travel bag. I plan to buy a couple more in the near future. One for my house. A cheap way to add security.
