Is it really safe to stay in a hotel when traveling or on business? Especially if you are traveling alone or staying in a hotel during traveling, you really need a door-stop alarm. Once a criminal intrudes into the room, the sounding alarm will not only deter the criminals, but also remind you and your neighbors to avoid loss of property. The door block alarm uses a stainless steel pressure plate, which is more durable and pressure resistant. At the same time, the anti-slip damping primer will prevent the door from being pushed open and thieves from entering. Aside from hotel uses, it can be used to avoid danger outside. After all, the device is easy to carry for protecting your own safety!
