Mengshen 3-Pack Safety Wedge Door Stop Alarm Stopper Blocking Travel Home Security Alert 120db (Pack of 3) MS-M68

Light, easy to use, has 3 levels of alarms and works a treat. Used it in London at the hotel and felt safe and secure

A simple device that does what it says. Even on low sensitivity, it is quick to go off and the alarm is loud, so no chance people won't hear it.

Excellent

I have had one of these alarms for years I use it at home and abroad especially when travelling on my own. This one was purchased for a friend who now travels a lot with work, I also purchased one for my niece for use at university

Seems good it but unfortunately it didn't work on my carpet floor.

I take this on all my solo trips abroad and in this country and can sleep well at night knowing no-one can get into my hotel room. Works really well. Once in place, the door can't move at all.

I bought this as I was cat sitting in a very large house on my own and was quite apprehensive about it. I used this on the bedroom door and it gave me peace of mind as it is a very loud alarm and would surely scare anyone who broke in.The only downside is that it wouldn't work on a door that was very close to the floor as there wouldn't be enough room for the door to travel far enough up it's slope to activate the alarm. It worked extremely well for me.

Alarm is quite loud. Max. Sensitivity setting maybe too much if door rattles with wind, post man, etc. Less sensitive setting avoids nuisance tripping.Negatives; if a door has very little clearance with the floor, i.e., less than 5mm, this door alarm would need something like a credit card laid on top of metal strike plate so that the credit card contacts the floor beneath the door in order to trip.
