2 Packs Upgraded Door Stop Alarm Portable Wedge Door Stoppers Security Alarm 120db Entrance Alert Loud Door Stop Alarm for Travel Home Apartment or Dorm (2 Packs)

UNIT IS WELL MADE, WORKS EVEN BETTER THAN EXPECTED, BATTERIES ONLY USED WHEN UNIT IS ALARMED SO SHOULD LAST FOR A LONG TIME, ANTI SKID COATING ON BASE IS SILICON AND REALLY STICKS TO FLOOR MAKING UNIT EASY TO USE. BEING ON FLOOR MAKES IT NEARLY INVISIBLE AND VERY HARD TO GET AT BY INTRUDERS

This product does exactly what I want/need it to do.Perfect product for my overall peace of mind.

The stopper is simple,easy to use and loud. The stopper will stop the door being pushed in and shriek at the same time. I use it, I gave my single daughter a set,and bought two more sets for my girlfriends. It’s not an alarm system but it does it’s job especially that loud piercing sound when door is pushed just a bit.

Which is what U want! Love it. Used many times

Nice and loud
