Very Compact, Very Loud
Bought these to alert us to take on holiday for alerting us if our SEN children were trying to make an escape from the holiday home: these things are LOUD, even on the lowest setting. Very good deterrent and after trying to escape once, the children didnât do it again.

Wedge door alarms
Door alarms which have aloud warning if triggered by the door being opened. It has a switch to switch on and off, and a second switch to choose 3 sensitivity settings. It is so simple to use and solid construction with a gripper to stop it from moving. I think the unit is great value for money

Simple but effective
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.

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

Make last minute security issues less of a problem!
Does what it says. However, unlike some others, it also works very well on laminated and wooden flooring. It’s lightweight, and appears sturdy enough to receive a good bashing, although by then and opportunist would’ve likely left.Size is decent and easy to pack, eg, slim enough to fit under mant doors but high enough for doors with larger gaps.It’s more practical than aesthetically pleasing and provides a nice secure feel to sleep in various accommodations where a non-locking door becomes a last minute challenge.Baring in mind we’re not security experts, this is loud!!! So if you’re planning your use it in your hotel room(?)1) Test the door against it to name sure you’re comfortable with its level of movement resistance/grip. Then2) Remove the batteries.

Very loud alarm
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 loud enough.
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.

Although it looks kind of unpromising, I guarantee that this is a very useful safety product if you are having a small budget. When kept under door this retricts from opening the door. Have to place a battery for the alarm. And trust me the alarm sound is quite frightening, so I guess this will definitely frighten the inwanted intruders. There is a on/off button so you can also turn it off if you do not want it. I also use this , so that kids can not enter my office during meeting. Its a veru useful product. Definitely recommend.

Perfecto para poner en la puerta de entrada a casa. Si intentan mover la puerta salta una sirena, con un volumen muy fuerte para ahuyentar al ladrón… Se puede ajustar la sensibilidad según presión que reciba.

This works so well. I forgot it was there the first morning, opened the hotel door and it immediately jammed and screamed so loudly I got such a shock. But that means it works perfectly. My mum loved it so much when I visited home and showed her that she kept it, so I’m going to have to order a new one for myself. Highly recommend. Makes me feel much safer as I do a lot of travelling.
