AceMining Door Stopper Alarm with 120dB Siren, Floor Mount Type, Rubber Security Door Wedge for Home, Hotel, Travel, Black

Purchased for a trip abroad. It came in handy since they put us in an adjoining room. It was easy to take with us and using it was a breeze. Would definitely recommend it. The only thing - the spring came out on one of them when I was taking out the battery. Other than that - they were great.

I am very happy with my purchase though it does not fit underneath my door for my front door of my home however it does work for the more lower doors inside of my home so I know it will work perfectly for a hotel door but I really purchased it for it to be placed at the front door but because my door is not flushed with the floor and sits a little higher up from the floor this does not work however once that battery is placed in which is a 9-volt and you click it to be on and back alarm goes off it will wake up everything in the house anyone not turn off until you turn it off

Just tried this in my hotel room, very easy to use and alarm is very loud.

Bulkier than I would have imagined. There is a larger lip on the front than I would have liked which limits its ability to get into certain spots. They function fine, but the design is not very user friendly.

Great product

Comes just as advertised

I felt secure while traveling and staying in hotels.

Bought these after seeing a review for use in a hotel room. I bought them for my daughter who will be living alone. They do work on two double AA batteries
