tiiweeDoor Alarm Sensors 120dB – Set of 2 Door or Window Open Contact Burglar Alarm for Your Home – 4 Modes – Easy to Install

This is an excellent item which has many advantages. The alarms are small and are easily installed by means of the adhesive strips included. The instruction booklet is very well written and illustrated and was easy to understand. 120dB is a loud alarm which you could not miss! The alarms can be set to sound either when a door or window is open or closed and will continue to sound for two minutes but there is also an option where the alarm merely beeps when a door is opened so that you know that someone has come in. The alarms are white and each comes complete with three LR44 button batteries; all I had to do was remove the strip of plastic to activate each alarm. These alarms give additional reassurance and do not need resetting each time you leave the house unlike a conventional alarm. We use one of ours in addition to the house alarm and the second one is installed on the garage door of our motor home to warn us of any intruders.

The media could not be loaded.  My lovely retired neighbour next door was burgled a few weeks ago and i had to go get this for my home. Does exactly what I need it to do , I like the fact that it is loud. I have installed one in the front door and one in the back door. Its been a few days since installed and no complaints.

I affixed one of the pair (the box has 2 items) as intended, the other had to be affixed upside down because the wider available space is on the door side (not the frame side). Both works perfectly.

As a basic door or window alarm these are brilliant as they are very loud, up to a point they could potentially damage your hearing. They have four settings, all of them usefull in their own way. Setting 1 goes off when the door is opened but it doesn't stop for a minute or so even if the door is closed again. 2 is in door chime mode. 3 alarm mode but does stop when the door is closed again, but if the door is left open it will also stop after a minute or so. 4 beeps constantly to let you know your door is open and it needs to be closed again. The alarm stops working if the door is left open over a minute in any mode except to let you know the door is open in setting 4 as the magnet needs to be in contact with the main unit to reset itself. It is simply there to let you know if your door is opened for any reason while you are in the house and while it could potentially deter unwanted visitors, it is not designed to be a full alarm system.

Very small and therefore easy to hide shed alarm. Comes with every thing you need to install and also very easy to fit. Very LOUD and can be heard from a fair distance (ask my neighbours!). Highly recommended.

Does what it needs to but really flimsy. Often just comes apart when I'm trying to chabge the settings. Very flimsy.

Very good, compact little gadget. Multiple settings. Alarm, Beep or loud Tone.Easy install and very loud. Just what I wanted.

Like how they have different settings, good value for money. In testing them before attaching them to my door they worked and were unbearably loud - exactly what you want. Thankfully haven't had to see them in action yet and hope not to have to!

Ça fait je pense 2 semaines que jes les utilise et j'ai déjà changé 4x les piles. Pour peu que l'alarme déclenche 2sec byebye les pile.Donc pour le coup assez moyen je dirais

Die kleinen, günstigen Alarmanlagen erfüllen absolut ihren Zweck. Sie sind leicht zu montieren und sind sehr laut. Wie haben sie nun seit über einem Jahr im einsatz und sie geben ein gutes Gefühl und tun ihren Job. Sie Batterien mussten seither nicht erneuert werden.

Produit de qualité. Très simple d’utilisation, cette alarme rententit puissamment et le double face est extrêmement efficace.Je recommande fortement

Installato sulla porta di una persona anziana per segnalare apertura porta segnale acustico molto chiaro e forte - semplice da montare ed intuitivo preso in offerto con i prime day - ha 3 tipi di allarme oltre al tastino di accensione e spegnimento corredato già di batterie consigliato

La verdad es que compré este producto por las valoraciones que tenía y he de reconocer que me ha sorprendido gratamente. Es sencillo pero a la vez tiene un sonido muy muy potente. Espero que dure (porque ya he tenido otros similares y no han durado mucho). Lo recomiendo totalmente.
