Portable Door Stopper Alarm for Hotels and Home

A portable door blocker for travellers, people who live alone and anyone who wants extra peace of mind behind a closed door. Place it under the door edge and tighten the knob so the foot presses against the floor; the textured base resists sliding and, if someone tries to push the door, the built-in alarm sounds. Light enough to pack in a suitcase for hotel rooms or rentals. Red plastic body with a metal foot. The supplier states 80 dB or more and a 5 V working voltage. Made by Jiadu. In the box: one door stopper.
