Blocklock Portable Door Locks for Travelers Security, Tough & Durable, Apartment and Home Door Security, Travel Essentials by Guard Dog Security, 2 Pack

This is sturdy and strong. I feel reliable. If you’re renting an aparment without deadbolts, this is a must. Also if a person has a big dog that messes with a pole type door jam (esp. one with an alarm), this lock is pretty dog proof. It doesnt require a battery, that's a plus. I recommend this product.

For anyone wanting peace of mind and simplicity this is worth it. takes 2 seconds to do. and then i have peace of mind when sleeping or just doing anything inside. congrats to person who invented these

As advertised. Would definitely recommend.

This is a simple and cost effective way to feel safer in my apartment building and also when traveling! Easy to use and a great value.

This product came well packaged, very easy to use in case of any emergency. It’s compact enough for me to even carry it in my purse

They're not small and look quite sturdy!!!

The slide is too short for some doors.

These locks didn't fit even ONE DOOR in the house, a complete waste of time and money. They ARE well constructed and heavy duty but if they don't fit your size door....

For done reason this item didn't work in my door , the plate in door couldn't hold the block lock

It doesn't work on all doors that you would expect them to.
