Awesome product!
Awesome. Definitely has served the purpose we needed it for. We are impressed with how well it holds the door placed on hardwood floor .....as well as...just how LOUD the 3 alarm settings are. We would purchase again and would recommend. Several people we've shown it to have said they were going to get one. Great value for the money. Easy for an 80 yr old woman to handle and use. Stopped the door with no problem. Altho small, quite sturdy. Clean sleek look.

Good sense of security.
Got these to have a better sense of security at hotel/motels. I place them wedged under each door. The alarm is really loud and you would be able to sleep through. The are very sturdy and have a rubber backing so they stay put and wont allow the door to open. Super easy to set up and put in place.

Great safety alert for travelling. Helps me relax and sleep better knowing there is an LOUD alarm to wake me if my room is being entered.

Bad Ass Security Device
These things are solid and do the job. They are loud and do wake up the dead. It's built and designed with some thought. Used at recent stay at a local casino and forgot it was below the door and it scared the heck out of me and my wife. Used in both hotel doors. One door that goes to the room next door and the main entrance. Super price for a great product.

It's loud and could scare off potential intruders.
This product does not fit under all doors. However, it's great if you have the right door.
