Review on TOWODE Door Stop Alarm 3-Pack - Upgraded Door Stoppers with 120 dB 🚪 Security Alarm - Perfect Gift for Travelling, Hotels, Homes, Apartments - Door Stopper Security Tools by Monica Cox

I had high hopes for them because they seemed so easy. Well, they didn't stick to the floor at all, even when I tried to slide them under the door (which might set off the alarm). Tried on parquet and linoleum on the floor/doors. Maybe it will turn out with a carpet, I'm not sure. The alarm itself went off when I manually pressed it myself. Not only could we not get him to turn on the alarm, we couldn't get him to prevent the door from opening either. Full bust from our point of view. Luckily, Revain has an excellent returns policy. I would look elsewhere. In the end we bought an alarm system for the bay.
