I have one . The alarm is super loud! I used to travel a lot for work, so I used it on the hotel room doors for safety
Love it. It is very loud,and I will use it in my hotel room at nights when I travel.
Nice works well, loud very well. but take better antislip pads for under contact to the floor. recommended seller.
Very good, tested it and it's bloody loud, plus is sensitive and as soon you open the door, it rings! you can't not hear it!!! Fully recommend the seller! And the quality of it is good.
